SBF 5.0/5.8L Magnum Hyd. Roller Cam 276HR

The COMP Cams SBF 5.0/5.8L Magnum Hydraulic Roller Cam 276HR (part number 35-312-8) is a purpose-built hydraulic roller camshaft engineered for small block Ford engines seeking mid-range performance gains without sacrificing streetability. This camshaft delivers 0.544-inch intake and 0.560-inch exhaust lift across a 276-degree intake and 280-degree exhaust duration profile, with a 114-degree lobe separation angle optimized for the 2000–6000 RPM powerband where most street and light competition engines operate effectively.

The 276HR's hydraulic roller design reduces valvetrain noise and wear compared to solid lifter designs while maintaining precision valve timing control. The moderate lift figures and 114 LSA create a cam profile that balances cylinder charging efficiency with drivability, avoiding the radical timing characteristics that reduce low-end torque and idle quality. COMP Cams' grind specifications are engineered to work within OEM small block Ford head casting and intake manifold geometry, making installation straightforward for builders using stock or near-stock engine architecture. The hydraulic roller design automatically compensates for minor thermal expansion, eliminating the need for manual lash adjustment that solid roller profiles demand.

This camshaft is engineered for small block Ford engine builders and enthusiasts upgrading from factory cam profiles to unlock additional horsepower and torque without requiring a complete valvetrain overhaul. The 276HR suits street rods, restorations, weekend track cars, and light performance builds where reliable idle quality and daily drivability matter alongside measurable power gains. Builders appreciate the COMP Cams reputation for consistent grind tolerances and quality control, making this cam a dependable choice for serious small block Ford projects demanding both reliability and genuine performance improvement over stock specifications.
