Lookin at 427 bbc(not tall/truck block) brodix bb2plus heads.(cc'd at 116), srp piston #141637 prox 9.5 to 1, comp solid roller # 11-703-9 .680 lift. vic jr. intake, 800 dp holly. bassett tt headers. There aren't many .070 pistons out there , but if this combo is going to suck I'll pop for a new block. I'm considering/ have been talking a little to cstraub, wondering if a custom grind would be worth the extra $$?? Any sugestions would be greatly appreciated. OH BTW it's going in a jet boat.
