COMP Cams Ford Small Block Camshaft Complete Kit FS XE258 HR10

The COMP Cams Xtreme Energy camshaft delivers enhanced street performance for Ford Small Block engines, producing very strong torque and horsepower gains with a smooth idle and responsive throttle—ideal for mild performance upgrades and heavy vehicle applications. Engineered for excellent low- to mid-range power, it performs best with proven combinations such as the Edelbrock Performer intake manifold and a TCI Street Rodder or stock torque converter. Featuring full-size base circles, this camshaft works seamlessly with COMP Cams Evolution hydraulic roller tappets and eliminates the need for dog bones and lifter retainers—components never intended for pre-1985 applications. This camshaft supersedes part number K31-412-8, offering a dependable upgrade designed for improved drivability and consistent performance.
