SBE 318 basic rebuild +CAM , INTAKE, HEADS, expectations?

on a 9.5:1 318 with ported 302's and a MP P4452761 (.450/.455 268/272 110LSA) with a performer RPM and 750 3310 i laid down a respectable 330hp @ 5750

with aftermarket heads and a airgap, i don't see why you couldn't be in the 350 range as long as keep the compression up. chasing much more than that requires a bigger cam that will only lessen the street manners while narrowing the power band and move it higher in the RPM range.

fwiw, a melling MTD-1 would come in fairly similar numbers wise and would be a good VFM pick if you're not going for all out power.
