How much does “UnderCover Porting” help the cast iron Vortec head ‘602 crate?  The stock ‘602 Crate Motor produced 349 horsepower @ 6,000 rpm.  With UnderCover Ported heads and our "Look-A-Like" parts the same motor made 363 horsepower @ 6,000 rpm.  Torque also increased 18 ft.lbs at 5,500 rpm.

Next, we installed our Crate Master Camshaft. The lobe centers and duration of the cam have been changed to improve performance; the valve lift was not changed.

The combination of UnderCover Ported heads and our ‘602 Crate Master Camshaft improved the motor 36 horsepower and 31 ft.lbs of torque.
