    Hey guys i've been calculating (or trying, i'm more of an english guy, horrible at math) all day trying to figure my compression ratio.

    What I get with a 4.155 bore, 3.5 stroke, 67cc heads, and flat top pistons is about 10.6:1...

    My question is, can I run at that lvl on 93 octane gasoline? If not, is there any thing I can do without changing my hardparts to make it run on pump gas without castrating it?
