Thanks everyone for the responses. Seems like 10.5-11.5ish compression with the correct cam should be fine. What do people do to pick a cam and have cranking compression end up where it needs to be? Is that adding more duration? Or overlap? Just curious what would be different in a pump gas cam compared to a high compression/race fuel cam? I would leave spec'ing the cam to the professionals, more just curious ow they would be different.

Dwayne spec'd the cams in both of my motors. The 440's cam is a more radical profile...pretty much race only. Yet you see the compression difference.

My little 440 makes my Hemi sound like a 383, lol.
