COMP Cams Dual Energy Cam and Lifter Kits
These Dual Energy cam and lifter kits from COMP Cams have more exhaust duration and lift than intake. They are designed for applications where a slight sacrifice in low-end power is acceptable for an increase in mid and upper-range rpm horsepower. These kits are ideal for use with restricted exhaust port cylinder heads, or applications using a full-length exhaust system.
