Hi, just a couple quick questions. I just bought a 86 vette, the guy I bought it from had bought a new 350 short block. he then had it bored .30 over, new cam and pistons and rockers, and he put on a set of aluminum edelbrock SMALL port heads. My question is, with these parts, do you guys think the PROM or computer need to be upgraded, he said he didnt do anything to the PROM or computer. The car is pretty fast, he said the car had about 400 horsepower. I cant really get it to a dyno to find that out, but it is fast.
