  1. 9.23:1 compression on 87 octane?

    I'm building up the 350 in my truck, and I'll list the specs below, but the real question is: can I run 9.23:1 compression on 87 octane unleaded with .040" quench distance without detonating? P.S. I will not change my heads to vortec, don't try to convince me, and my cam choice is staying too...
