    ITS good to see theres a few people out there that are aware we exist!
    but any "GURU status "
    is only the result of LEARNING from a ton of mistakes made, in the past, and the willingness to share what experience the more experienced members on the site have gained, and pointing out what did or did NOT work well.

    or as my dad said

    "only an idiot touches the red hot stove burner TWICE, most of us LEARN from our mistakes"
    &

    "if your going to be DUMB, you better be TOUGH because life's going to be hard & expensive, its better to be observant and learn from OTHER PEOPLES MISTAKES"

    CHECK ALL YOUR FUSES and electrical connections WITH A MULTI METER, but don,t assume you know what the problem is, let the facts lead you to the answers
    be aware that not all engine "MISSES" or "ticking sounds " that you might be dealing with or tying to correct, are an electrical or a fuel delivery or pressure issue, your problem might be a mechanical issue like a vacuum leak, from a busted hose,or loose gasket,a burnt valve, loose or worn timing chain,badly adjusted valves, broken or loose harmonic damper, loose flex plate, or torque converter bolt, busted valve spring, burnt or defective rocker, loose or worn valve guide, or a dozen other issues so try to logically isolate it to a cylinder or system, electrical,valve train, fuel delivery, exhaust , ignition ,etc.
    Ill add these tips.
    it usually helps, if your posting about a problem, and looking for help, if you post your physical location IE city & state as there are frequently local members with experience that might be willing to help diagnose and maybe help with the mechanical or electrical or tuning issues too cure the problem.

    (1) do EXTENSIVE research FIRST, before....... buying parts.... or starting a modification, that INCLUDES making a detailed parts list and researching , the sources, cost, manuals etc. IE FIND OUT whats necessary to do the job, and what results youll expect before you start

    (2) ITS a HUGE advantage to have the correct tools, things like engine cranes, diagnostic test equipment, welders,lifts, etc. may seem like a big expence thats not dirrectly moving your project forward, but there NECESSARY in some cases and ALWAYS make the project go faster and easier than trying to do without them.

    (3) work SAFELY, if you could get hurt doing something, chances are very good that you will eventually find out exactly WHY you should have done it the safe rather than the fast/easy way, if you don,t think it thru and use the correct tools and precautions

    (4)ITs almost ALWAYS better to have several friends help, on a project, having two or more guys thinking things thru improves your chances of getting it done correctly and safely,and keep in mind ,its always best to do your projects after helping a more experianced guy do something similar on his car so you have some experiance doing it, thus be ready and available to help your buddies withn thier projects and don,t avoid helping so you won,t get dirty, or have some free time thats used on other guys cars vs yours...in the long run it pays big to help others

    (5)ask questions and be sure you understand the answers, KNOWING what your doing before you start is a huge advantage

    (6)take pictures, label wireing, put small parts in labeled ziploc bags and take notes, use the manuals, and internet, and if something won,t fit or looks wrong research rather than forcing it with a bigger hammer

    IF you start with checking for loose electrical connections and vacuum leaks you might find the problem, a propane torch is both safer and easier to use as a method to locate vacuum leaks
    check for vacuum leaks

    [​IMG]
    (DONT LIGHT IT) just SLIGHTLY open the valve so its allowing gas to flow at a low volume,start the engine and let it idle at the lowest speed you can then place the tip of the UNLIT torch at any suspected vacuum leak and listen for the rpms to increase and watch the tachometer, gas flowing into a vacuum leak will increase engine speed.
    Another possible quick test you can do relates to "clear flooded engine mode" if the car cranks but doesn't start and has fuel pressure, you can test by trying disconnecting the TPS sensor connection on the pass side of the throttle body,. This will kick the computer into limp home mode (setting a predetermined voltage) and the car will start after a time if you flooded the plenum in the intake
    look for loose or missing vacuum hoses, cracked or broken power brake connections, emissions system hoses that are loose, vacuum connections to the trans or ignition, loose connectors missing or loose bolts cracked hoses missing accessory connections etc.
    naturally this only locates leaks to the outside, and its possible for the intake to suck air from the lifter gallery, so that also needs to be checked if everything else seems to be ok.

    read this


    buy a CHEVY SHOP MANUAL FOR YOUR YEAR CORVETTE!
    set and verify your ignition timing, pull trouble codes,set your tps and iac,, then check for vacuum leaks on the lines and intake,then get out your multi meter and verify all the sensors, chances are good its a defective heat sensor or defective o2 sensor, a logical step by step approach will lead you to the problem, youll be amazed at what youll learn reading links. use of a shop manual and multi meter can be very helpful

    a good quality if temp gun helps more than you might realize at diagnosing problems
    http://www.grainger.com/product/EXTECH- ... _-AllPages
    learn to use the factory shop manual, and a multi meter and LISTEN to the engine closely, tapping and high pitch whines can indicate defective injectors or fuel pressure regulators, fuel pumps,mis- adjusted valve train components, worn distributor parts, check all the fuses and electrical grounds and corrosion on connections thats something thats frequently over looked etc.

    HELLO to everyone. my name is christopher smith, and especially to you mr. grumpyvette. i have read a few of your posts and your recommendations and they make good sense. i like to think of myself as a little bit of an engine guy. i understand enough to get into deep trouble. actually i was with an outfit called "engine source" and used to hot tank, bore, hone, deck, grind, surface, etc engine blocks and parts.

    here's the story. got a 70 1/2 split bumper true z28. has a 4 11 rear end in her, with a turbo 400 trans. 468 cubic inch with an extreme energy 274h competition cam products, 3" exhaust, hooker headers, gm 781 oval port heads, with and edelbrock torker II intake, 750 holley double pumper, roller rockers etc...

    ran her out of oil a few years back and it is time to get her going again. i am thinking about upgrading the camshaft. i am keeping it at 468 cubes, about 9.7 compression ration, 2.19 on the intakes, 1.88 on the exhaust, and keeping her hydraulic because my daughter is 17 and wants to run at the track. so i'm thinking a 12 second camaro is fine for a 17 year old girl. the frame is connected and she has the frame tied and an 8 point cage and a line lock. the Z was built and then you have the kid and well you park the car and you go to work... and then one day, wellllllllllllllllllllllll...

    so since i am going to do whatever is needed to the crank and or rods, i am thinking about the Lunati VooDoo 60204. i am fully aware of matching the springs etc etc...

    what i am asking is what you think of the 60204 for a 9.5 compression ration 468. yes i will match the torque convertor. i am thinking about leaving the 750 on until she becomes more familiar with the car.

    any thoughts????

    Welcome Christopher !!! We like to think you came to the right place.

    That should be plenty for your 17 yo daughter to get her feet wet. You do know that this will just
    bring more boys around. Does she like coming out to the garage and helping yet ???

    There is just one thing I need to let you know !

    comp cams xe274 vrs lunati 60204....

    hey to everyone.....

    i got your email and yes i agree with the air gap intake manifold, and yes i have a very large scoop (open end toward windshield) on the car.

    i am looking to create a torque monster using a 468 cubic inch big block chevy engine. my "low budget" 496 peanut port iron headed street engine had 120 cc chamber with a static compression ratio of 9.7:1. yep, i wrote static. that's cuz i had the engine block decked, line honed, tru-blok bored and honed, and all kinds of other machine work done. she spun very well.

    this was also a "roller hydraulic" camshaft in this 496.... this was a truly nice street engine, dependable, easy to start, drive, rip the eye teeth out when your passanger when i ran 10 lbs of air in the Mickey Thompson Street ET's. here are actual dyno number on that engine from way back when. i do not have a scanner so i can not scan yet, nor do i know how to paste pictures YET.. but then again, i have a 17 year old and if she can't i bet one of those boys can....

    that was a 595 ft lb / 520 horse 496. now i am doing the 468 and i really want the bottom end torque of a stump puller that will make a 300 to 400 foot ride just wild. think i can get those kinda numbers out of a 468 with a set of 781 and a 60204 lunati camshaft? i know i do not have the stroke and i also do not have the piston speed as a 496, but i am looking to come close.

    any suggestions???

    thanks in advance,
    chris

    AT one time I owned a 1961 and a 1968,corvette, then I got married and only owned a 1968, then things got tight and that eventually had to go..I then bought a 1985, and a 1996, and the son bought a 1992 that spent 90% of its time at my house with me doing all the maintenance and repairs at my cost.
    I still own the 1996 and 1985, but currently the 1985 is being slowly refurbished.
    when I got married my wife knew my hobbys were elk hunting and building engines and rebuilding corvettes , I told her jokingly that I might consider giving up elk hunting for a full time mistress, but I was keeping the cars, and tools, but she saw elk hunting two weeks a year, and the cars as a bit less of a problem than the potential mistress for some reason.

    Reading links was almost a fulltime job to me for a while, but it pay at the end.
    Am not reading alot latelly i must admit, i can't afford to work on anything, so my interest for cars and engines are reduced.
    Anyway am so thirst for learning. There's always a grey area where i want to expand my knowledges, so the link still picks my curiosity.

    Some of the links are not working anymore(the ones pointing to forum post using viewtopic.php)

    The projects topic with alot of pictures and jokes are mostly what am here for.(learning and having a great time with great people)

    as many of the longer term members on the site know,
    I try hard to collect and post as much related info as I can collect,
    and place it here on this site, comment on the content as I think its required and add what I thinks missing or over looked.
    yes a few links will be rather repetitive,at times, because I don,t know what your skipping over, or reading through!
    one of my pet peeves is having someone delete a damn good knowledge source! or fail to put any personal effort, at all, into learning whats required!
    we are all here to help!
    one thing I really hate is going to a semi trusted web site to retrieve info, only to find that source is no longer there as the web sires been deleted, I posted for years on several web sites only to have two I had zero control over suddenly dis-appear as the web sites owner was not able to keep up with the sites expenses and eventually just "threw in the towel" I'm trying hard to keep this site open, long term as a dependable resource but at times its difficult!

    Amen, some of the links are repetitive, but read them and take in the knowledge and learn from the mistakes others have made and be better for it!

    theres a bunch of us old geezers on this web site
    well its good to see someone takes advantage of 5 decades of my personal experience and
    dozens of other very experienced and in many cases even more skilled members ,
    who are also posting, answers from in many cases even more personal experience.
    when you have a cumulative total of hundreds of years of success and without doubt a few screw-ups,
    too look back on, it gives you a much more realistic look at this hobby

    I'm always glad to help when I can!:D

    and if anyone takes the time to read the links and sub-links,
    they can,t help but pick up a good deal of hard won tips,
    and yeah experience comes from making mistakes,
    wisdom comes from remembering and avoiding mistakes,
    that you and others have made previously, and keeping notes on what worked well.
