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.
