Comp Cams High Energy and Dual Energy cams for the Ford 351C and 351/400 M engines.
High Energy™ Cam These high torque cams work very well on the street. Designed for use in carbureted engines having a 9:1 CR or less. Can be used in conjunction with most stock components, including intake and exhaust manifolds, and carburetors. Normally, gas mileage will either remain the same or increase over a stock cam.
Dual Energy™ Cam These cams have more exhaust duration and lift than intake. Designed for applications where a slight sacrifice in low end is acceptable for an increase in mid and upper range RPM horsepower. They may be used in conjunction with an exhaust system that is much more restrictive than the intake system.
