    I have been more of a chassis man than engine man until I got hooked up with this site. Rick (Indycars) is a local bucket head and his posts has me thinking about new directions for my build.
    The original plan was take my “low mileage” (sent all for sale low mileage lol) stick my blower on it and go down the road. But noooooo! Now I’m thinking about a better combination for longevity. I guess finding this site is going to be expensive! Thanks pals! Lol

    yeah! thats one of my problems also, I rarely want to jump blindly ,into projects simply because,
    I know all too well from decades of experience that it always take a bit longer and costs significantly more,
    to do things correctly, too select the best parts you can afford, to get the machine work done CORRECTLY,
    and accurately measure, and then as usually required,
    carefully clearance and assemble the parts,
    than most of the younger guys, who are generally pushing to get the project done understand
    on the plus side,
    most projects force you to learn new skills and justifies the purchase of,
    or forces you too acquire new tools ,
    you'll generally make new contacts, gain experience, maybe make new friends,
    and once complete your usually pleased with what you built,
    and proud of what you've accomplished,
    and the process will usually kick up the respect for your skills and experience among,
    those guys you hang out with.

    Thank you Grumpy. I look forward to the journey. At 73 I hope I’m not to old to learn new tricks.

    I'll answer that. You are NEVER too old to learn something new!!

    Do you have an idea of your budget and torque/hp wants?

    You have to start somewhere with a budget, then a parts list to match the budget and then re-adjust
    the budget and then revised parts list and then a new budget and then ..... well you get the idea.

    Excel or Apache Open Office (Free) will make this alot easier. I guess you will be back over with your computer
    soon !!! LOL !

    Hp Costs Money $.
    It can be done 1000 Hp on a budget but likely fail.
    The Premise of this entire site lately.

    I been thinking about the motor budget and it makes my head hurt! Lol. I don’t know if I should go with my original plan and go with a simple cam and seal and gasket “rebuild” and get running and spend time and money on the bad ass motor later. The budget can’t stand the car and motor at the same time!

    I have several cars.
    To build all top notch costs more than I paid for my farmhouse and 5 acres.
    TA gets the best.

    this is not a cheap hobby, but personally I've always regretted in the long term any time I've done any work I knew,
    could have been significantly improved on, or when I could have used better quality parts.
    if you look at the whole project you easily get over whelmed,
    its better to list out each sub-component or system and work on either its acquisition or correctly completing the proper assembly,
    of each sub-assembly before moving to the next section.
    break the project down to
    block,
    rotating assembly
    heads
    valve train
    lube system
    cooling,
    ignition
    exhaust
    induction
    fuel supply
    drive train
    transmission
    frame
    suspension
    interior
    body
    wiring
    gauges
    sensors
    brakes

    having the correct tool to verify the engines operational temps would be helpful

    Rick has a good idea.
    Spread sheet layout.
    Budget plan.
    Take all from savings buy it.
    Or how much you can afford to spend weekly and monthly.
    Set a Time date to complete all.

    When I built my first blown street car I was racing with Pete Robinson and his SOHC Ford front motored top fuel car. I was going for ported and polished heads and all the trick stuff. His advice was to go to the junk yard and get a truck motor (they all had 8.0 to 1 compression back then) and run it until the crank came through the oil pan and go get another motor.
    The heads developed a leak where he brazed a hole to the water jacket so I replaced the heads with 283 2 barrel heads and could see no difference in power. Ran them for 8 more years. Have any of you guys had a blown motor in a street car weighing 2,000 pounds? I could out run motorcycles. It was before crotch rockets but a 750 Norton was no slouch!’

    You can build so its 100% nostalgic period correct just like back in the day.
    I like them like that too.

    Grumpy likes everything modern Tech .
    Most all aftermatket.

    I like both.
    With Pontiac Factory Iron.
    Race parts hidden inside.

    Only problem is period correct parts are hard to find in Mint shape.

    It snowballs fast.

    To my thoughts its not wise to not take full advatage of modern forged 4340 connecting Rods.
    Modern pistons too.
    If ran hard a Forged crank is a good idea.

    Also Grumpy and me both agree a 700R4 or 4L60E is a bad idea.
    Do not listen to other guys in the Corvette world....story in itself.

    Grumpy likes 4L80e.
    I Like Turbo 400.
    Both can be pounded on relentless and not fail.

    I’m thinking a 200 4r modded like Rick. I won’t be beating on it. With these little cars things happen so fast you need to drive real conservatively not to hurt myself or somebody. It is mostly eye candy but capable of incredible performance! A blown motor pulls like a bitch as long as you hold the throttle down.

    John look at engine masters, they got 750 hp from a stock block 350. But if went with a DART block, decent rotation assy, mild flat tappet cam , good set of aluminum heads, you could build one to last.
