COMP CAMS CL31-491-9 COMP Cams CL31-491-9 Xtreme Energy Hydraulic Roller Camshaft and Lifter Kit for Small Block Ford

Upgrade your Small Block Ford engine with the COMP Cams CL31-491-9 Xtreme Energy camshaft and lifter kit. This matched valvetrain package combines a hydraulic roller camshaft with compatible roller lifters to deliver a performance-oriented combination for street and performance applications. The camshaft features 0.480-inch lift at both the intake and exhaust valves, with 258 degrees of duration on the intake and 266 degrees on the exhaust, providing a balanced profile for strong engine response across the operating range.
The 110-degree lobe separation angle supports a responsive powerband and performance-focused engine character. With a recommended operating range of 1,200 to 4,800 RPM, this Xtreme Energy profile is designed for engines that need usable low- and mid-range performance rather than an extreme high-RPM-only setup. The hydraulic roller design helps provide consistent valve action while reducing the maintenance associated with mechanical lash adjustment.
The COMP Cams CL31-491-9 kit is designed specifically for Small Block Ford applications and provides the convenience of installing the camshaft and lifters as a coordinated package. It is a practical choice for engine builders and enthusiasts completing a street performance, restoration, or mild competition build. Always verify engine compatibility, valve-to-piston clearance, spring specifications, pushrod length, and related valvetrain requirements before installation to ensure proper fitment and reliable operation.
