thoughts on 351 vs 306 - Page 2

I would think it would be good. Whats the power range for that cam? 545/565 should be pretty good.

I would check the dynamic compression with cam specs and engine specs.Also would figure out the quench pad area to see if its tight enough.
From just looking at the flow numbers on the pc heads the low and mid lift numbers are a little low adding all the lift numbers together those fall shorter than you think compared to some of the supposedly lesser heads.jmho

Naturally aspirated I would think for them to work decent you would need to have pretty low gearing and launch it at high rpms there fore requiring a little more carb and cam.The larger cam would need more static compression to keep dcr up either way their will be a compromise somewhere.But if you are going to juice it all the time they should respond good

Better yet, find a 351 from a '94 up F/E series (F4TE block), they're roller blocks.
