BBC Gen VI Xtreme Hyd. Roller Cam XR294HR-10

The BBC Gen VI Xtreme Hyd. Roller Cam XR294HR-10 from COMP CAMS is a purpose-built hydraulic roller camshaft engineered for big-block Chevy engines demanding high-performance street and strip power. This camshaft is designed for builders and enthusiasts who need reliable valve actuation across a wide RPM range without the complexity of solid roller maintenance. The hydraulic roller design automatically adjusts lash during operation, eliminating the need for manual valve adjustments and providing consistent performance in demanding applications.

Built with COMP CAMS' proven Xtreme Energy profile, the XR294HR-10 delivers 0.540-inch intake lift and 0.560-inch exhaust lift with 294-degree intake and 300-degree exhaust duration at 0.050-inch valve lift. The 110-degree lobe separation angle optimizes overlap characteristics for broad torque delivery from 2800 to 6200 RPM, making it suitable for both street cruising and high-revving performance scenarios. The hydraulic roller lifter design reduces valvetrain friction and wear while maintaining precise valve timing, contributing to improved fuel efficiency and extended component longevity compared to solid roller alternatives.

This camshaft is ideal for big-block Chevy Gen VI engine platforms, including modern crate engine builds and restorations where drivability and reliability are priorities. Installation requires proper timing gear indexing and verification of lifter clearance; users should confirm compatibility with existing intake manifold and valve cover configurations before ordering. The compact 24.55-inch length accommodates standard big-block Chevy bearing saddles, and the camshaft pairs seamlessly with factory or aftermarket hydraulic roller lifter sets designed for this platform.
