if you're gonna build a 283 i would try and get a corvette fuel injection for it, use a stock 283 crank dont overbore it if you want it to last, leave it closer to stock bore, use all light weight heavy duty parts on the bottom, and build a valve train made for spinning HIGH rpms, thats the way 283s make power is revving like crazy, get some heads made for flowing right with the fuel injection, i've never messed with a classic vette injection system so i dont know how tuneable they are....next put a 5 speed behind the car, use a good heavy duty rearend with like a 4.56 gear, possibly a ford 9", get a 4link kit for your car so your rearend will hook up, use the best clutch money can buy, and dont forget to put brakes on the car cause you'll need um..... i'm sure you could pull under 12s with that setup.... its gonna cost you a lot though.... and probably cause a few headaches along the way since a high rpm 283 (which is what a 283 is best used for) has not so much torque, you're gonna need that rear gear to make up for the loss of torque, and a good launch
