COMP Cams CL33-422-11 Xtreme Energy 218/224 Retro-Fit Hydraulic Roller Cam and Lifter Kit for Ford 352-428

The COMP Cams CL33-422-11 is an Xtreme Energy Retro-Fit Hydraulic Roller Cam and Lifter Kit engineered for Ford FE big block engines displacing 352–428 cubic inches (1963–1977). Designed for serious street performance builds, this kit delivers strong mid-range torque and improved throttle response, and works especially well with aftermarket headers.

COMP Cams Xtreme Energy hydraulic roller camshafts use an aggressive lobe profile to extract more top-end horsepower and better throttle response than comparable flat tappet grinds, while still maintaining usable engine vacuum for street-driven vehicles. The retro-fit hydraulic roller design allows modern roller lifter technology to be used in engines originally equipped with flat tappet camshafts.
