Help me find the umph in my 360

I don't know what size the combustion chambers are on a Speedmaster head, but for what it's worth, the pistons in my 360 (67 Barracuda) are .100 in the hole at TDC. With 62 cc Indy LAX heads and .24-.28 thick composition head gaskets my CR calculates to 9.5 to one, give or take a tenth or two depending on the actual head gasket thickness. Not ideal, and not the best setup for quench, but it works well enough I'm not gonna spend $$$$$$ to rebuild the motor. And it doesn't lack for low end torque. In fact, it will burn a set of street tires all the way through low gear. That's why I'm running Nitto 275/60/15 drag radials on the street.

But if the OP's CR is 8:1, milling the heads and running thinner head gaskets will bump the CR up significantly. Personally, I don't think the OP's cam is too much for his setup if it were properly tuned and had a better torque converter. But then what do I know?? :realcrazy:
