BBC Xtreme Roller Cam XR280R-10

The Comp Cams BBC Xtreme Roller Cam XR280R-10 is a high-performance roller camshaft designed specifically for big-block Chevrolet engines. It is ideal for builders seeking aggressive lift and extended duration for both street and strip applications. This cam profile is engineered to deliver the aggressive valve timing necessary for peak horsepower in modified BBC powerplants.

The XR280R-10 features precision roller lifter technology, which reduces friction and wear compared to flat-tappet designs. This allows for higher spring pressures and more aggressive ramp rates, translating to improved scavenging and cylinder filling at elevated RPM ranges. The roller design enables steeper lobe profiles and faster valve actuation, enhancing overall performance.

Serious BBC builders and performance shops rely on the XR280R-10 for consistent results in 454, 460, and 496 big-block applications. This camshaft is engineered to work seamlessly with modern valvetrain components, ensuring reliable performance when properly calibrated to your specific BBC configuration and intended power band.
