11 to 1 on pump gas

StrokerScamp said

My slant is comin up with like 8.67 DCR and 10.482 SCR. I wasn't tryin to be contrary with you, just that I've read different stuff. All this DCR stuff is kinda new to me anyway, so any help is a plus.

Well altitude(sp)? plays a big part also. I will be running I think it is 8.8-8.9 DCR with magnum heads and 91 octane in Ca at sea level. Brian at IMM said he ran this same setup in INDIO Ca which is below sea level and ran fine. I will be mixing gas for break in though. After that i will carry some 110 in the trunk to mix just in case. But If I run 91 on 8.8-8.9 which most are saying needs 93 then I will be a happy kid! :burnout:
