SBC Magnum Hyd. Roller Cam 286HR

The SBC Magnum Hydraulic Roller Cam 286HR from COMP CAMS is specifically designed for small-block Chevrolet engines that require enhanced valve-train performance without the maintenance complexities associated with solid roller setups. This camshaft is ideal for builders and enthusiasts aiming for aggressive lift and duration specifications while ensuring reliability and adjustability through its hydraulic roller design.

The hydraulic roller design utilizes pressurized oil to maintain zero lash automatically, which eliminates the need for manual adjustments and minimizes valve-train wear compared to mechanical or solid roller alternatives. The cam features precision-ground lobes made from hardened steel, which reduces friction and enhances component longevity, especially during high-RPM operations. With a duration profile of 286 degrees, it is engineered to deliver robust mid-range torque and peak power, making it suitable for engines operating within the 2,000–6,500 RPM range.

This camshaft is compatible with all hydraulic roller small-block Chevrolet engines, including Gen I and Gen II blocks, provided they have the appropriate roller lifter packages. Its design ensures consistent performance across numerous heat cycles, which is crucial for reliability in modified engines that run on pump gas or mild nitrous oxide. Whether for a street machine, a weekend warrior, or a performance truck, the 286HR camshaft is an excellent choice for enhancing engine performance.
