COMP CAMS K31-492-9 COMP Cams K31-492-9 Xtreme Energy Small Block Ford Hydraulic Roller Camshaft and K-Kit

Upgrade your small-block Ford engine with the COMP Cams K31-492-9 Xtreme Energy K-Kit, a coordinated performance package designed for street and strip applications. This complete kit combines a hydraulic roller camshaft with matched lifters, valve springs, and timing components, helping simplify component selection and installation while supporting dependable valvetrain performance. The camshaft is engineered for responsive throttle action, strong mid-range power, and practical street manners.
The hydraulic roller camshaft delivers 0.514-inch intake lift and 0.509-inch exhaust lift, with advertised duration ratings of 264 degrees intake and 272 degrees exhaust. Its 110-degree lobe separation angle supports a performance-oriented power curve with a noticeable increase in engine response. The recommended operating range is 1,500 to 5,500 RPM, making this combination well suited to performance-focused small-block Ford builds that need usable power across a broad portion of the engine speed range.
COMP Cams designs the Xtreme Energy K31-492-9 as a matched system rather than a collection of unrelated parts. The included hydraulic roller lifters, valve springs, and timing set are selected to complement the camshaft’s lift, duration, and operating range. This approach can help streamline an engine build and provide a cohesive foundation for upgraded street engines, weekend performance vehicles, and other small-block Ford applications. Verify cylinder head, piston, rocker arm, retainer, and spring clearance requirements before installation, and follow COMP Cams setup and break-in recommendations for the selected combination.
