Xtreme Energy Hyd. Cam - BBM XR280HR-10

The Xtreme Energy Hyd. Cam - BBM XR280HR-10 is a high-performance hydraulic roller camshaft specifically engineered for Big Block Mopar B and RB-series engines. This component is ideal for street-focused enthusiasts who demand a significant increase in mid-range torque and top-end power without compromising driveability. By modernizing the valvetrain with a roller profile, it addresses the inherent friction limitations of older flat tappet designs found in classic muscle car powerplants. This camshaft provides the necessary airflow improvements to revitalize heavy-displacement engines used in performance applications.

Technically, the Xtreme Energy Hyd. Cam - BBM XR280HR-10 utilizes a hydraulic roller configuration that allows for more aggressive lobe profiles and faster valve opening rates. It features a valve lift of 0.541 inches on the intake and 0.537 inches on the exhaust side, paired with an advertised duration of 280 and 288 respectively. The 110-degree lobe separation angle is optimized to balance a broad power curve with a performance-oriented idle quality. Operating within a 2200 to 6000 RPM range, the design ensures reliable performance and longevity under high-stress conditions.

Owners of 383, 400, and 440 cubic inch engines will benefit most from this upgrade, particularly when seeking a more aggressive power profile for street or strip use. This camshaft is a direct fit for Big Block Mopar B and RB-series blocks, though it requires compatible hydraulic roller lifters and appropriate valve springs for correct operation. Professional installation is encouraged to verify timing and ensure all internal clearances meet the required specifications for high-performance builds. Utilizing this COMP CAMS technology ensures your classic Mopar remains competitive and reliable on the modern road.
