so, i bought this 350 crate engine (4-bolt) with vortec heads from this cat at work. i get the bastard home, pull off the heads & oil pan, the damn thing looks like new (not bad for $250 ). let's talk performance! i bought a moroso oil pump & pan, that's it to date. i really like the edelbrock performer rpm air gap intake. what kind of cam would i need to make 400hp with these parts? i've built a couple of cars, but this is my first foray into building my own engine, so i kind of know whats going on, and i don't know dick about cams yet. i was thinking of a comp cam? what about carb(s)?
