COMP Cams Dual Energy Camshafts
COMP Cams Dual Energy camshafts have more exhaust duration and lift than intake. They're designed for applications where a slight sacrifice in low-end power is acceptable for an increase in mid- and upper-range rpm horsepower. These cams are ideal for use with restricted exhaust port cylinder heads, or applications using a full-length exhaust system. Select the model and options designed for your vehicle and engine application.
