Chris, this engine uses the "peanut port" head, now I have nothing against peanuts BUT these things do have limited airflow. Not knowing more specs, especialy camshaft, I'd guess that you installed some sort of a aftermarket cam (judging from you other component selection). With a mild profile I'd say you should produce around 485 to 500 ft/lbs of torque at 2800 RPM and 360 to 370 HP at 4700 RPM. This may seem like a low power number, but I'm assuming stock heads with stock valve sizes! A guy would have to have more data to accuratly predict the outcome of this project! - DRHP
