SBC Magnum Hyd. Roller Cam 314HR

The SBC Magnum Hyd. Roller Cam 314HR by COMP CAMS is a purpose-built hydraulic roller camshaft engineered for small-block Chevrolet engines seeking reliable mid-range performance gains. This cam profile is designed for builders and enthusiasts who want measurable horsepower and torque improvements without sacrificing drivability or requiring extensive engine modifications. Whether you're building a street engine, weekend warrior, or looking to refresh an aging small-block platform, the 314HR delivers the lift and duration characteristics that maximize efficiency across the RPM range.

Hydraulic roller technology provides superior accuracy and repeatability compared to traditional flat-tappet designs, reducing wear on valve train components and enabling tighter tolerances throughout the valvetrain. The roller profile minimizes friction losses and extends cam lobe life, while the hydraulic lifter design self-adjusts for zero lash operation—eliminating the need for manual valve adjustment and allowing the engine to idle smoothly across varying load conditions. COMP CAMS' precision manufacturing ensures each lobe is ground to exacting specifications, delivering consistent valve timing and lift that translates directly to combustion efficiency and measurable performance gains.

This camshaft is ideal for small-block Chevrolet platforms equipped with hydraulic roller lifter systems and compatible valvetrain geometry. The 314HR profile suits street and strip applications where the goal is balanced power delivery without extreme RPM demands or radical valve train requirements. Installation requires standard cam replacement procedures, proper pushrod length verification, and confirmation that your cylinder heads accept hydraulic roller lifters—most modern Chevrolet performance and OEM heads support this technology. Pair this cam with a quality intake manifold, carburetor or fuel injection tuning, and a compatible ignition curve for optimal results.
