    I just had a rather long and detailed discussion with a guy who it was all too obvious ,was basically trying to get me to give him a detailed list of engine components to build his engine.
    now thats hardly rare, and Ive had similar discussions a hundred times, Ive build a whole lot of engines and seen a whole lot more than those built and raced, and 95% of the time the guys building or racing those cars have made mistakes that were eventually corrected.
    many guys either insist on using components they own currently or think they can buy far less expensively that the components, I know from experience will actually work.
    but the thing that made me crazy during this discussion, was that Id ask specific questions, as to his goals, his budget, his skills and what he wanted to accomplish, and then suggest parts,, not necessarily a brand or a specific part number most of the time, but Id suggest something like find a deal on some cylinder heads that have about a 210cc port, 2.02 intake valves and flow in the 270-280cfm range at .600 lift and list detailed reasons why I thought those parts were a good match to reach his listed goal, and it was all too obvious that his real goal was to get me to suggest he use, or approve of or some how validate a huge list of totally miss matched, and mostly stock components, components that I strongly suspect he all ready owns, that were never going to allow him too reach his stated goals as to power and rpm range etc..
    Cylinder Pressure Note: youll generally want to try hard to maximize the useable compression as the higher the compression before you get into detonation the more efficiently the fuel can be burnt and the more torque the engine can produce, if limited to pump high test 92-93 octane fuel,165 psi # of cylinder pressure is about the best cylinder pressure for Iron heads with 92-93 octane, using pure un-ethanol laced fuel, gasoline. while the faster heat transfer rate of aluminum cylinder heads will usually allow 190psi # as the upper limit or best for aluminum heads.
    anyone can slap together parts and a few get lucky and find a combo that runs fairly well, but the chances wildly favor those guys that take the time to follow well known previously successful engine combos or at lease very similar builds

    look, I,m probably never going to see this guy, Ill never make a single dime on his build and theres no possible reason Id want him to do anything but succeed with his build and be happy with the result, I don,t get anything, no financial kick backs or commissions, But I would like to see him reach his goals and not waste a ton of money and time building something thats doomed from the start to be restricting his potential power levels to far below his stated goals.
    I started and maintain this web site mostly on my own dime with some very appreciated assistance occasionally, but its whole purpose is to help prevent the members from going thru the decades of frustration, wasted cash, mistakes and wasted effort I went thru and many (most) of my friends went thru before we learned some basic facts about what WILL and what WON,T generally work well when building a car, an engine or a garage and related subjects.
    keep in mind your very unlikely to find a problem thats unique , or build something that someone else has not already built or at least built something very similar, so do some research, and follow previous successful car builds, look over those similar builds and be aware that knowing how the previous guys solved similar problems, can save you a great deal of time and effort, and if you want an engine that makes lets say 600 hp the best route is to duplicate a previous successful build that reached or exceeded that goal, not throwing together random components and hoping your combo will work.
    heres some basics that won,t change theres a couple thousand related threads here to help you.
    You may find this a bit different from other forums, as I can assure you I spend about 97% of my time on this site adding links info and valid additional text, where its needed in older threads as I see the need, I don,t think youll find many threads that are 6-8 months old or older that have not had additional sub links or pictures or text added

    you need a decent , dry, level place to work, and at least some decent tools, you don,t need a huge garage, a 10' x10' shed or a single car garage, with a level concrete floor might do, but you do need a safe place to lock up and store tools and parts
    a few hour or days of research can save you weeks of wasted effort, and having skilled friends helps so make as many contacts as you can in the hobby.
    it helps to have friends that are willing to help.
    find a decent quality machine shop you can trust.
    parts and machine work always cost more than you think they will.
    you need a plan with a well researched and detailed parts list.
    youll need a decent engine stand and an engine crane if you do many engine builds.
    lighter weight cars tend to be faster and easier to stop, and break fewer parts.
    even a great engine matched to the wrong drive train or gear ratios will be well down on performance.
    access too an air compressor , a drill press and a decent welder and a few accessories helps a great deal.
    you NEED decent dependable transportation, and thats NOT going to be your performance car project.
    any money you spend on parts that don,t match your well researched list , no matter what kind of a "DEAL" you get is likely to be wasted cash.
    you will NEVER have the best or fastest car, unless bill gates is paying your bills,
    but that certainly will not prevent you from having a really nice car., persistence and a well though thru plan are the key.
    don,t get frustrated,everything you do is likely to take 2-5 times longer that you expect and cost more money, its part of the hobby, take the time to improve your skills, acquire parts and tools and make contacts in the hobby.

    busterrm solid fixture here in the forum

    I love it, my best friend is one that just throws together mismatched parts and expects the moon. I have made that mistake with one engine in the last 4-5 yrs and won't do it again. I am planning a build right now and have a list but it seems to change daily. hahahahahaha!!! Thanks Grumpy, very good post friend!

    By David Reher, Reher-Morrison Racing Engines

    “Here’s a Reher analogy you’ve never read before: A racing engine is like a bowl of Jello.”

    My daily fitness regimen is a brisk morning walk at Texas Raceway near my home in Kennedale, Texas. It’s just me, my dog, and a drag strip.

    It’s quiet there on a weekday morning, and a man can think. Among things I’ve been thinking about recently are the common mistakes that racers make. One of the biggest errors is collecting parts for an engine that will be built “someday.”

    Some racers build engines on the installment plan by stockpiling parts over a period of time. I know that a limited racing budget often dictates when parts can be purchased. However, the problem with this plan is that better parts are constantly being developed. Many components that were state-of-the-art a few years ago are now far behind the development curve. I think it’s a better strategy to collect the money to build an engine with current technology than to collect obsolete parts.

    The pace of change in engine technology is accelerating. I see the evidence whenever I walk through our shop. Piston rings for sportsman engines rival the rings used in Pro Stock just a few years, at a fraction of the cost. Precision-machined dry-sump oil pumps that were once reserved for high-end engines can now be bought for a third of the price. Some sportsman cylinder heads can now outperform the extensively welded and modified castings that the pros used just a few years ago. And when I look at the valves and springs available now, I am amazed by the progress that’s been made in metallurgy.

    It doesn’t take long for components to become obsolete. If you’d asked me two years ago about cylinder heads, rocker arms, and cam profiles, my recommendations today would almost certainly be different. My advice back then wasn’t wrong – it was simply based on what was available at the time. If you intend to race in the fast eliminators that have become popular with sportsman racers, then you can’t expect to be competitive with “antique” parts, even if they are only a few years old.

    Another potential pitfall of buying parts piecemeal is ending up with an unworkable combination. Consider the staggering variety of big-block Chevrolet cylinder heads on the market – conventional ports, raised ports, spread ports, symmetrical ports, 18-degree heads, 14-degree heads, and many other variations. Each distinctive design requires specific complementary components, from intake manifolds and pistons to rocker arms, gaskets, and valve covers. Consequently that trick manifold introduced in 2010 may not work with the cylinder heads you buy next month.

    It’s painful when a customer brings a pile of mismatched parts into our shop and asks me to build an engine out of them. I hate to turn business away, but I have a responsibility to be honest when someone shows up with a collection of incompatible parts. When a customer asks me to put a set of CNC-machined large-port cylinder heads on a marine engine that’s going to cruise at 3500 rpm, I really have to point out that he’d be much happier with smaller ports.

    Here’s a Reher analogy you’ve never read before: A racing engine is like a bowl of Jello. Why? Because you can’t wiggle a bowl of Jello in just one place. Touch one part and the whole thing moves. To continue the metaphor, you can’t change just one part of a racing engine without affecting the entire combination. Change the intake manifold, and you may need to change the cam, the carburetor, and perhaps even the rearend gear ratio to get maximum performance with a new setup.

    It’s easier than ever to purchase parts through online auction sites, virtual speed shops, and manufacturer websites. But are those parts in your shopping cart really the best for your application? Are they compatible? Are they high-quality components or cheap knock-offs? Before you hit the “Buy” button, it’s worthwhile talking with people who have real-world experience with building, testing, developing, and maintaining race engines.

    Let’s say you buy pistons that are advertised as having a 14:1 compression ratio. And when you assemble the engine, you discover the actual ratio is 11:1 because the valve pockets and domes are designed to clear any conceivable cam/valve/cylinder head combination. A universal piston isn’t going to be effective and efficient in a serious racing engine. You don’t need or want .300-inch piston-to-valve clearance, but that may be what you get unless you talk with an expert.

    There is no shortage of Internet experts who claim to have all the answers on engine building. Unfortunately, some keyboard gurus have little practical experience. I see endless discussions about rod length-to-stroke ratios on forums and bulletin boards, yet on the list of important factors in engine performance, rod ratio ranks about fiftieth. And please don’t get me started on cylinder head flow numbers. CFM is one of the least important characteristics of a competition cylinder head. Two head designs can have identical flow numbers, yet one will rev up and run on a racing engine, while the other is as flat as West Texas. In level of importance, the average air speed, port shape, and the efficiency characteristics of the port rank much higher than simple CFM numbers. Yet these vital characteristics are often overlooked, and most cylinder heads are sold on the basis of CFM figures.

    Drag racing is a technology-driven sport that is continuously evolving. The winners constantly look for the next step forward, not yesterday’s hot setup.

    When the Mark IV was installed in production vehicles for the first time in 1965, it carried the Turbo-Jet name on the air cleaner, displaced 396 cubic inches, and was rated at a maximum of 425 horsepower in the Corvettes.

    Here’s a quick look at milestones in the big-block’s expanding and contracting history of displacement:

    396 cid – introduced in 1965, with 4.094-in. x 3.760-in. bore and stroke (first production Mark IV engine).

    427 cid – introduced in 1966, with 4.250-in. x 3.760-in. bore and stroke (aluminum versions used in COPO supercars).

    366 cid – introduced in 1968, with 3.935-in. x 3.760-in. bore and stroke (tall-deck; used in truck applications).

    402 cid – introduced in 1970, with 4.125-in. x 3.760-in. bore and stroke (advertised as 396 cid).

    454 cid – introduced in 1970, with 4.250-in. x 4.000-in. bore and stroke.

    502 cid – introduced in 1988, with 4.466-in. x 4.000-in. bore and stroke (Gen V block, originally developed for non-automotive applications; adapted later by Chevrolet Performance).

    572 cid – introduced in 2003, with 4.560-in. x 4.375-in. bore and stroke (developed by Chevrolet Performance; no production vehicle applications).


    the longer exhaust duration and wide LSA is an advantage if the exhaust is restrictive.it provides more time for the mass of exhaust gases to exit the cylinders,keep in mind its that properly timed exhaust that drags in the following intake charge.
    if your using open long tube headers with the proper length primary and collector design,to match your displacement ,compression ratio, and cam timing, longer exhaust duration rarely provides a useful advantage.

    there's a bit of discussion on cam selection in the thread links posted above and in this thread, notice the cam selected is far from the most radical that might fit the application,and there's discussion on the differential gearing intake selection and trans gearing and converter stall speed, and while the cam and heads selected were not (BY DESIGN) the components that would cost the least or produce the best peak power numbers they ARE well matched and can quite easily do two things, provide dependable and instantly available and impressive torque, and allow the car to drive without problems on the street, something, in the cars drive-able characteristics, that a much more aggressive cam, that makes a bit more peak power would most likely not provide.
    this is a factor that a great many people don,t grasp or understand, and thats correctly matching the combos characteristics to the true intended application, it makes no sense to build a 600 hp sbc that produces peak power at 6700 rpm if your car has a transmission and gearing that restrict its operation to the 1500 rpm-6300 rpm range, yet I constantly see guys read the magazine articles in places like stock car magazine and decide to try and duplicate some 600 hp plus combo they read about on a street car engine build, then they proceed to really screw it up further because they decide that the expensive cylinder heads and block machine work can be ignored to save money, so they substitute much less expensive components and don,t match the drive train and gearing and act stunned and amazed when the combo of mis-matched components runs like crap, gets into detonation issues and surges and bucks at anything under 4500 rpm.

    Im always amazed frankly at guys that insist they need a certain cylinder head port CC size for an engine, especially when I doubt theres been much if any time spent actually doing the required calculations required to find the correct cross sectional area of an engines intake port or manifold runner length, and you can,t possibly do that required math with out matching the engines displacement, compression ratio, intended power band,rear gear ratio, tire size,cam timing (lift & duration) valve curtain size, after measuring the cylinder head port cross sectional area, and header primary size and length.
    THINK THROUGH YOUR OPTIONS AND THE COMPLETE COMBO,
    I see guys have long discussions about things like the difference in port cross sectional area or the best connecting rod length, to use, no one factor is going to make your engine totally dominate the competition, its a combo of small almost insignificant individual component choices being made and a good deal of time and effort taken during the assembly and clearancing work, that stack up to give you or prevent you from maximizing the engines performance.
    you may not even think about factors like polishing crank journals, or valve train geometry or intake runner cross sectioinal area or length ,or intake runner port matching or surface finish, but the combined effects of your choices and components selected do mater!
    look guys I think a good deal of this discussion is missing the point here, Ive built well over 150 engines in the last 45 years, (I lost cound decades ago)
    but I can assure you that longer rods and the easily verifyable slight increase in dwell time, the longer rods produce will be totally meaningless UNLESS, you design the engine for and select components too take full advantage of the minor increase, by carefully calculating the REQUIRED compression ratio,fuel octane required,all the factors related to the cam timing,(duration,lift, LCA) you calculate and build and install, and tune the engine for , a matched exhaust header scavenging (header primairy length and diameter plus collector design) and the intake runner length and cross sectional area, to maximize the cylinder scavenging effects, plus you match the fuel/air ratio, and ignition advance curve, to maximize that longer dwell times potential advantage.

    I often have guys state they NEED a 180cc or 170CC port head to maintain low speed torque, then the same guys insist they need a VIC JR single plane intake and a 750 cfm holley double pumper carb, (for better peak power) and they will also point out the need for RAMS HORN EXHAUST MANIFOLDS to maintain good flow but save the cost of headers..obviously the list of mis-matched parts selected could be endless, the main point is that guys read some magazine article , and assume the limited info they read, is valid! (and not knowing that most of the stuff not being mentioned, and purposely over looked is critical) like the fact the car has a 4.11:1 rear gear and a 3200 rpm stall converter, ported heads, and extensive tuning, a non-stock ignition, and other mods.. and then they mistakenly assume the little info they do see, relates to every possible combo.
    guys come away from reading the magazine articles, thinking all, thats required to built a killer engine, is slapping a listed cam and vortec heads with some trick intake manifold on a low compression 350 sbc to run killer times and do endless burn-outs

    the very mention of the fact that theres MATH formulas available to actually calculate the correct matched components has never once been mentioned, and when it is I get that deer in the head lights stare or Im ignored as an OBVIOUS JERK who is just out to piss on their pizza , as they have read through several magazine articles so they know exactly whats needed!
    selecting the CORRECT MATCHING CYLINDER HEADS is not a randomly made choice if your doing it correctly, its a process of matching the needs of the engines requirements under known or at least expected conditions.
    yes its a KNOWN process with well understood MATH and REQUIRED testing, if your not following a know recipe exactly.

    mention the fact theres actual tests for ideal fuel /air ratio, exhaust back pressure in the exhaust system,and intake plenum vacuum , fuel distribution, bearing surface speeds, rpm limitations , and ignition timing , valve float, air flow rates in the intake ports , port stall and they look at you like you are 9 feet tall and just stepped of a flying saucer

    While cheat sheets might have frowned upon in your sixth-grade classroom, we strongly encourage them in the garage, shop, or pits. That’s why we’ve put together this list of 13 key performance formulas you should know when building or tuning your street or race vehicle.

    why is it that darn near everyone just reads a few magazine articles and assumes that when they show remarkable gains from a cam swap that they don,t mentally step back and ask what to me is an obvious question, "WHAT DID YOU DO THAT YOU FAILED TO MENTION?" like new valve springs ,new rockers, larger injectors porting etc. look the fact is that most stock valve trains are not designed to run at over 6000rpm, and most cars have injectors sized for the original power level, and most cars have automatic transmissions and rear gear ratios , and compression ratios more designed to lower emissions and increase mileage than to maximize peak power, so swapping a new more aggressive cam MANDATES other changes, like long tube low restriction headers and a low restriction exhaust behind the headers, to allow it to function to its full potential, and additions like an additional trans fluid cooler to math the higher heat produced by a higher stall speed torque converter and a different rear gear ratio, and better valve springs, higher cost roller rockers and porting the heads and intake is conveniently ignored,and that the original stock parts won,t work well with the new performance cam, without the parts they forgot to mention when that miracle cam jumped the peak power 80 plus hp is simply ignored, as posting that info might reduce sales of the cam the articles pushing for sale are not compatible with a noticeably longer duration cam. its the combo of small improvements and intelligently selected matched components that adds up, to allow you to build an impressive engine.
    choices like upgrading from the stock rocker arms on an Lt1/Lt4 to a set of quality aftermarket full roller rockers with a 1.6:1 ratio might only produce small gains by themselves but
    keep in mind that on an LT1/LT4 engine, in a corvette, that had about a 330-350 hp rating, the rockers having a gain of 12hp-17hp like I mentioned is about a 4%-5% boost, while its not going to pin you back in the seat during acceleration it might put you an extra 8-10 feet ahead in a 1/4 mile drag race as you go through the lights compared to the old combo

    spending a few days or even weeks doing careful research well before you start writing checks or pulling out a credit card, can save you thousands of dollars and months of work, understanding the difference in component quality ,correct clearances and how and why each component is supposed to perform and the potential stress its under helps you make far more intellegent choices and tends to allow you to get an engine built that far exceeds the quality and performance of the average crate engine assembly

    YES ONE OF THE THINGS ALMOST ALL MAGAZINE ENGINE BUILDS, SKIP!
    they purposely
    SKIP OVER IS THE LONG MACHINE SHOP AND PART ORDER TIME FRAMES,
    SHOP LABOR COSTS,
    AND MOST CASH CONSUMING DETAILS, on the ENGINE BUILDS
    little things like having to spend 45 hours porting the heads and intake,or clearance milling the block, or welding on the oil pan,to get them functioning correctly, or having to junk the original valves and valve springs and retainers to get the proper geometry, just get ignored
    and concentrate on promoting this month favored part vendors product
    most engine builds are at best thinly disguised advertisements for some vendor, or LIST OF VENDORS components
    notice the list of manufacturers commonly listed in the article

    youll rarely if ever see any detailed description of the valve train components
    what the exact valve train clearances were the type of valves used the multi angle valve jobs
    the back cuts on valves
    what the part number was on the valves, or keepers, retainer, valve springs, shims cups clearances.

    thats simply because, of experience!
    lets assume you have a 1969 camaro , that looks great like this
    [​IMG]

    with several aluminum or fiberglass components and get the weight down near 3200 lbs with you in the car!
    I learned decades ago that you can have choices and choices have concequences,spin a small efficient , high compression (12.5:1) engine , like a 302 sbc with a carefully assembled solid lifter valve train to 7500-8000 rpm
    and make lets say 1.5 hp per cubic inch (302 x 1.5-or 1.6:1 = about 450 hp- maybe even 480 hp) and use expensive race octane fuel, which gets constantly more expensive and limits what you can do and where you can go with the car,
    or you can build a 496 BBC,
    now lets say you build it to have 10.5:1 compression so you can run it on premium pump 95 octane(hard but not impossible to find, especially if you are willing to add some octane booster occasionally.
    4200 fpm with a 302 and its 3" stroke = 8400 rpm
    lets say you cam that 302 so your making 350 ft lbs at 7000-rpm. thats 466 hp
    or you build the 496 and make lets say 1.3 hp per cubic inch, and 1.3 ft lbs per cubic inch of displacement and with its 4.25" stroke the same 4200 fpm, limits you to, about 6000 rpm.
    the 496 BBC makes nearly 645 hp and 645 ft lbs, and while it weights about 100 lbs more and might cost an additional $1000-$2000 additional to build
    (remember the small blocks going to require an expensive valve train and decent forged components just like the BBC if you want both engines to last long term)
    lets say we go with a 4 speed muncie in the 302 and match it to a 12 bolt with 4.56:1 rear gears
    on the BBC we instal a 4l80R and a dana 60 so between the transmission, 3.55:1 rear differential and engine the BBC 496 car easily weights an aditional 330 lbs

    http://www.wallaceracing.com/et-hp-mph.php

    http://users.erols.com/srweiss/calcehp.htm

    your killer sbc in the 3200 lb camaro with its 466 flywheel hp is maybe at 400 rear wheel hp, that equates to about....Your ET / MPH computed from your vehicle weight of 3200 pounds and HP of 400 is running near, 11.65 seconds and MPH of 116.01 MPH.

    your much more street friendly 496 cubic inch pump gas BBC 3530 lb camaro has about 540 rear wheel hp
    Your ET / MPH computed from your vehicle weight of 3530 pounds and HP of 540 is running 10.89 seconds and MPH of 124.09 MPH.
    or close to a second faster, its much easier to drive and you can actually go on trips because if your careful pump gas can be used.
    think about the difference here, one car sounds impressive like a chain saw running nitro methane, its damn impressive running mid 11 second times at near 116 mph in the 1/4 mile but you don,t get to drive it much on the street because race octane fuel cost over $4 a gallon, and it runs like crap under 3500rpm

    on the other hand the BBC version runs pump high test (maybe a bit of octane booster) and costs you maybe an additional $3-$4 k to build but its damn near bullet proof and you can jump in and drive from Colorado to Miami if you wanted to with a more reasonable expectation of arriving without having had and issues.
    (keep in mind with 28" rear tires
    the manual muncie sbc car spins roughly 3800 rpm at 70 mph.
    the BBC version with the OD trans and the same tires is spinning about 2300 rpm on the same trip at 70 mph
    http://users.erols.com/srweiss/calcmph.htm

    yeah! thats one extremely common reason why guys fail to build a decent engine,
    I can,t begin to list the number of times I've had some guy ask me to build him an engine ,that will make 500,or 600 hp, for his muscle car, and when I explain whats involved in time and money to do it correctly,
    and propose a very detailed list of the required machine work and draw up a parts list,of a well tested , known combo, I've built, before
    without any doubt the first thing out of their mouths is the fact they want to substitute 1/2 of the parts for less expensive components,
    and skip 3/4's of the machine work and then use a few parts they already own
    they invariably are convinced that cheaper similar parts will work out fine and cost less!

    When I explain that we can follow their version but it won,t make anywhere near the same power,
    they generally can,t or won,t believe me.... at first!

    I generally say, look this is a bit like backing a cake, if the recipe, calls for 2 cups of cane sugar and that sugar costs $4, and you go to the local store and find you can buy SALT that looks identical, for 79 cents, you could use that and save almost 80% on the cost!
    both items are white granular substances, they look almost identical,, both are commonly used and there,s not a damn thing wrong with either product,
    but I can assure you the resulting "
    cake"or ENGINE, built using the less expensive substitute product will result in a much different finished result.
    then I point out that THEY will be buying the parts and paying the local machine shop bills for the things I don,t have the required , tools to complete, and I'm probably not going to make over $5 an hour for the week or mores time that the project will require.
    THEY WILL BE MAKING ALL THE DECISIONS, THEY WILL BE BUYING ALL THE PARTS,AND THEY WILL BE LEARNING A GOOD DEAL IN THE PROCESS ABOUT HOW AND WHY THINGS WORK THE WAY THEY DO!
    they have a choice, they can go to almost any local machine shop or buy a crate engine and in either case spend less money, but they are also not going to get the same end result.
    you can take your time, take advantage of decades of experience, and learn how and why things get done a certain way ,and measure and carefully clearance and fit components and do things correctly
    or
    you can buy and assemble any random list of parts, or buy a crate engine, in either case your car will probably be up and running in a few weeks,
    if you want things done correctly you,ll spend a good deal more time and probably 60%-to 200% more money , but I will not be making squat on the deal,but I will get a good deal of satisfaction from the end result.
    yes I enjoy the builds and enjoy teaching, and yes I love watching guys, who correctly built their engines, blow the doors off the guys who go the crate engine route , or slap together random components.....this is not and never has been a money making proposition, and I don,t work too a stop watch....if it takes longer and costs a good deal more thats the price of quality, ..but I do have a decent list of satisfied people who like the results they got from building their engine with a good bit of help, many have returned several times over the decades, and I sleep well knowing they did the job correctly.

    Yeah. That's funny. When is the last time you saw anyone that could actually make change for a dollar without the cash register telling them?

    I was recently over at a friends home where he showed me a back un-used bedroom,
    it was partly filled with a stack of boxes from summit, jegs etc.
    and he had a legal pad with a good percentage of the parts he wanted to use,
    listed and checked off,and it was obvious he had put a good deal of thought and money already into his dream car.
    He had that legal pad, where he had listed the exact components he had decided he needed to build,his dream car and its engine and drive train.
    I looked over the list and if he ever gets it completed and assembled he will have one kick-butt car & engine combo.
    I had to admire his determination, as his intention is to build a 540 cubic inch, centrifugally super charged, and intercooled,
    and fuel injected, big block chevy engine that should easily put 800hp to the rear wheels.
    he wants to put a 4l80e transmission and dana 60 rear differential in a 1969 camaro
    I'm fairly sure many of the guys reading through this don,t or have not dealt with, or built enough engines, and been involved with enough of the engine builds to realize the various manufacturers approach building components with a great many different objectives in mind,
    component parts vary and careful research and selection is required!
    I've always found SCAT and CROWER parts seem to be a good value!
    keep in mind the "weakest link in the chain" concept,
    Any logical engine builder needs to sellect components with a firm goal in mind and recognize the intended power band and rpm limitations.
    need there's not much sense in selecting a rotating assembly that is built to easily handle lets say 1200 hp and 7800 rpm, at 4500 fpm in piston speeds,
    if the block main caps walk at much lower stress levels, or if the block your thinking of using it in,will most likely have the caps walk well below that stress level.
    nore would it make sense, using such a high dollar rotating assembly if your going to match it with a valve train and hydraulic roller cam that floats valves at 6400 rpm, or heads that reach port stall at 6700 rpm
    have you ever taken the time, and effort,
    too step back and grab a legal pad and pen, and logically make a reasonably complete list of the parts you,ll need,
    and do the research required too list every part, (including all the small components like bolts, bearings gaskets) and their current cost, where you can find those components for sale, and part number, brand and supplier, and the phone numbers etc.
    and call a local machine shop to get a better idea as to the labor cost of a project your looking into starting?
    once you do theres commonly three things youll face,
    the first is generally a sense of being over whelmed and depressed at the un-expected,total projected cost!
    the second is a very common and strong temptation to either scrap the whole idea or to start substituting cheaper and generally considerably lower quality components that in the long run will eventually make the completed project either not worth owning and certainly something your less than proud to own.
    and the third is the strong tendency to purchase parts that you find for bargain priced that either are not well matched to the intended projects goals, or nearly useless when matched to the project goals, but the bargain price seems nearly impossible to pass on.

    all these tendency's result in a great many partly complete or abandoned projects, or projects that don,t resemble anything close to the original intent, or projects that never get started in the first place.
    the completion of a well designed project will take some detailed planing and the ability to stick with the original projects part list and goals, and doing your research in detail, as to both the parts and machine shop costs, the time required and in many cases the tools that you might need,and of course youll need a place to work and store the project while its being built or repaired, well before you start buying components

    I was impressed that he had taken the effort to select matched components like

    It really pays to step back and make a list of your basic goals, your skills, and to think through where your going to work on any project you start and think through what you want to have once its built, and realistically think about your budget, and the time it will take, and realize any budget you write out at the start of any muscle car restoration project,is likely to realistically be about 1/3 to 1/2 of the real price,by the time your finished and it runs correctly, you'll have a good grasp on the hobby.
    a good many guys start a project without listed goals, It helps to join a local car club to make contacts in this hobby so you can gain skills and get discounts on parts, and having several friends who are building similar cars rarely hurts either.
    and if you really don,t know what you want too be driving in a few years you can spend amazing amounts of cash on parts you really can,t use and waste a great deal of time on a car that your never going to be happy driving.
    but if you stop and think things through carefully and list the type of car, its engine and drive train, your favorite color, the type of interior, and other, characteristics, and then make a detailed list of the components and tools you,ll need and the skills you might need to acquire to build it, your much more likely to acomplish your goals and be happy with the results.

    each area has machine shops with different tools, experience and unfortunately some machinists have attitude issues
    and don,t seem to think delivering top quality work at reasonable prices and on promised delivery dates are a reasonable expectation.
