Acceptable LT1 compression?
After reworking the heads in my LT1 and installing bigger valves I come up with about 53CC. When I calculate the compression with these and the thinner Impala head gaskets I already bought it jumps from stock 10.4 to about 11.2. I am using a lingenfelter cam that specs at 213/219 with zero overlap. My question is if it will run OK on pump gas with this compression ratio?
Thanks,
Roy

It should. In my current combo, I'm running 11.3 CR and have no problems w/ 93 octane premium. My new shortblock will have a tight quench area and about the same CR which will make it even less prone to detonation.

...I know plenty over 12 to 1 running pump gas no prob, Just gotta have the right cam to pull it back a little, your current cam (even though it's on the mild side)should be alright with your new comp ratio
