I was advised to start a thread here for a pro charged 300. Looked high an low for someone who has done this didn't come up with nobody but doubt I'll be the first, between me an my machine shop were putting together a .40 over 300 with a fully ported and polished head with oversized valves along with some roller rockers, cam and pistons are still to be determined beins my original plan was to be naturally aspirated. Now after speaking with my machinist were goin with a p-1sc-1 pro charger, we agreed that ten pounds of boost is what were going to try to make it happy with.i have a offenhauser c series intake with some efi manifolds, my two questions is has anyone done anything with the Holley sniper efi setup? And what do the boosted 300 guys do for ignition/timing setups? This will be driven every chance I get an will be on 92 ethanol free pump gas.
