Thx Shawn, I will dig into your article and do more research. Since my motor is a stock 1984 truck motor with oval heads, I can pretty much assume my static compression will be low. My motor came out of a wrecker and I am geussing this thing is cam'd from the factory for all torque at low rpm's. Id like to bring that up a bit, but I am definitely not going to be reving this thing out.

Somewhere in between would be nice...
