Hi.. seeking some tech info, somebody who can do good math..
I have a 308 block that is 0.040" overbore (over original which is 4.0") using a Keith Black 719 flat top forged piston with a head volume of 4.8cc and rod length of 5.09" plus a Fel-Pro 1011-2 gasket which has a compressed volumed of 8.5cc (Gasket Bore: 4.100" and Nominal Compressed Thickness: 0.039"). I'm using this to get a good combo for my Kenne Bell Blowzilla with 8 lbs of boost. Also, the AFR 185 has a 3/4" deck thickness.
So using AFR 185 heads, does anybody know what is the best choice to get a CR 9:1? Is it the AFR 185 with 61cc combustion chamber OR the one with 58cc? I prefer the 58cc one that comes with a blower exhaust port of 75cc over original AFR 185 / 61cc chamber with only 69cc exhaust port.
If I only know what is the stock engine's stroke, I'd be able to find out.. is it 3.4" guys? and thanks!
