WHICH CAM

The static compression, rear gear ratio, torque converter specs, transmission gearing/type, and rear tire size will need to be known before making recommendations. Any idea what cylinder heads and intake are on it? Do you know how much head work you have and what the springs/guides/retainers will allow on lift? How was the horsepower determination made? Dyno, E.T./M.P.H., or based on a confirmed build? What's the vehicle weight?
