Again, thanks all of youfor your input. I do realize that 500 hp=money. my goal is to have 500hp=least $$ possible. Any specific suggestions would be great.

I've been looking at the AFR 195 heads, they seem to flow well, and I only hear good things about them. they're about 1300 shipped.

Anyone want to guess what kind of 1/4 mile an 81 camaro weighing 3600 with driver would turn pushing say, 475 hp with a good chassis hookin up well?

Anyone built a 500 hp 383 successfully? want to lend any tips? or even YOUR recipe? Thanks
