Sbc Cam 280H (Hyd)

The Sbc Cam 280H (Hyd) from COMP CAMS is a small block Chevy hydraulic flat tappet camshaft engineered for street and strip performance across a broad RPM range. This camshaft delivers predictable, responsive power delivery from idle through the 2000–6000 RPM operating window, making it ideal for builders seeking reliable performance without sacrificing drivability. Hydraulic flat tappet designs reduce valve train complexity and maintenance compared to solid lifter alternatives, while the symmetrical lift profile ensures balanced power across both intake and exhaust events.

The Sbc Cam 280H (Hyd) features 0.480-inch lift on both intake and exhaust valves with a 280-degree duration specification and 110-degree lobe separation angle (LSA). The 110 LSA geometry optimizes valve overlap and scavenging efficiency while maintaining a conservative power band suited to naturally aspirated small block applications. Hydraulic lifter actuation automatically compensates for thermal expansion and wear, eliminating the need for manual valve adjustment and ensuring consistent performance across varying engine temperatures. This design reduces complexity during installation and promotes long-term reliability in street-driven and competition environments alike.

The Sbc Cam 280H (Hyd) suits small block Chevy engines equipped with hydraulic valve lifters, including popular platforms like the 305, 327, 350, and 383 displacement variants. Installation requires confirmation that the engine block features hydraulic lifter bores—solid lifter conversions are not compatible with this camshaft. Engine builders, hot rod enthusiasts, and performance tuners choose this profile for street machines, truck builds, and circle track applications where mid-range torque and ease of maintenance outweigh peak power demands. Proper valve timing and intake manifold selection optimize the Sbc Cam 280H (Hyd) performance characteristics.
