I have seen this done to a chevett, get a truck frame, change suspension and shorten, remove unneded support, take a 350 and a muncie 4 spd out of a 70's camero and bolt everything in. You got a rocket that is heavy but will make up for it in hp's and torq. Or I could say, leave it stock and get going about 60- 70 Mph and run it into a tree and then get a real car. Just kidding about that, if you could make it look visually stock it would be a killer sleeper on the street also, really how many chevetts do you know of that is a true 13.00 second car? you would achive this approx with a 350.
