I am right at 11-1, maybe a just a little bit less, 68 427 SO block stroked with a Scat 428 crank, bored 16 thousands over, Rpm performer heads ported and polished using flat top Diamond pistons (with valve relief), comp cams 282s cam with flat tappet roller rockers. I use 93 octane and xylene as a fuel additive and the engine loves it.
