Machine Work Required for Forced Induction

I'm using a 72 360 block, if your going to be pushing 10+psi I'd say definatly get a set of H-Beam Rods. Even with a mild build your going to be looking at 500-600+ flywheel hp. If you go with Cometic Head Gaskets they recommend a 50 RA or finer surface on the block/head mating plane. I'm using stock main caps/bolts but if I did it again I might go with a stud kit. I am using an arp head stud kit. Even if you don't go with a stud kit on the mains having them align bored might be a good idea.
As far as pistons go, stay away from Hyperutectic on boosted applications. I'd go forged and think about a quench dome design. Anything you can do to reduce the chance of detonation is a definite plus.
I built a stroker and went with a forged crank..but a good cast crank should hold up below 500rwhp without any worries.
