Xtreme Hyd. Roller Cam - SBC XR269HR

The Xtreme Hydraulic Roller Cam - SBC XR269HR from COMP CAMS is a precision-engineered hydraulic roller camshaft designed for small block Chevy (SBC) engines seeking aggressive performance across a wide RPM range. This camshaft is purpose-built for enthusiasts and builders who demand enhanced lift, extended duration, and reliable valve control without the complexity of solid lifter adjustments. The hydraulic roller design automatically compensates for thermal expansion, making it an ideal choice for street performance, mild race applications, and engines operating in variable temperature conditions.

Engineered with 0.495-inch intake and 0.503-inch exhaust lift, the XR269HR delivers 269 degrees intake and 276 degrees exhaust duration, optimized around a 112-degree lobe separation angle (LSA) for strong mid-range torque and responsive power delivery. The hydraulic roller lifter system reduces parasitic friction losses compared to flat tappet designs while maintaining precise valve actuation from 1500 to 5500 RPM, where the cam's power band truly excels. This configuration strikes an excellent balance between street manners and performance, providing smooth idle quality and consistent performance across load conditions without requiring frequent valve lash adjustments.

The Xtreme Hydraulic Roller Cam suits small block Chevy engines from 1955–1996 platforms, including 305, 327, 350, and 400 cubic inch variants equipped with compatible hydraulic roller cam blocks. Installation requires a camshaft-compatible timing set, lifters rated for roller cam operation, and proper pushrod length verification to ensure optimal valve train geometry. Whether building a cruiser-performance engine, street machine, or mild competition platform, this cam delivers repeatable, reliable performance with the convenience of automatic lash adjustment and minimal maintenance requirements.
