Needsaresto; With using old 383 small chamber heads I was really talking about ways to take a stock 400 short block and try to build a dirt cheap motor that makes modest power. Its part of the debate about getting good power without getting a stroker kit and having all the machine work on the block. 25 years ago when I had very little money I did things like this all the time and street raced the hell out of junky combinations. One thing is for sure, trying to make good power with sub 9 to 1 comp and 400 or less cubes is not easy without power adders. You can't just throw in a big cam and expect it to work. I have no plans of throwing together any junk motors now so the post was only meant to be helpful to anyone who is doing this sort of thing.
