Horsepower and torque come from the right combination of intake, heads and camshaft. BluePrint Engines will test several brands of heads and camshafts to come up the best combination. By connecting the flow bench software to the "Cam Pro" machine and then downloading all data into the engine simulation software program we can accurately predict the results and dial in the best likely combination of parts before ever building an engine. In the case of this 383 cubic-inch circle track engine, a key goal was to achieve approximately 500 horsepower and 500 ft-lbs. of torque in an rpm range best suited to circle track racing.
