SBC Hyd Camshaft

The COMP CAMS SBC Hyd Camshaft (part number 12-105-3) is a factory muscle hydraulic flat tappet camshaft engineered for small block Chevrolet engines seeking reliable mid-range power and streetable performance characteristics. This camshaft combines a proven hydraulic valve train design with specifications optimized for naturally aspirated small block applications where drivability and longevity matter as much as output.

The hydraulic flat tappet design utilizes self-adjusting valve lifters, eliminating the need for manual lash adjustment and accommodating normal engine wear over extended service intervals. This camshaft delivers 0.390-inch intake lift and 0.410-inch exhaust lift across a 319-degree intake and 320-degree exhaust duration window, centered at a 112-degree lobe separation angle. The power band spans 600 RPM idle stability through 4,800 RPM peak performance, making this profile well-suited for street engines where smooth low-end torque and predictable mid-range response are essential. The factory muscle classification indicates this grind sits in the moderate performance tier—more aggressive than stock profiles but practical for daily-driven builds prioritizing reliability and part compatibility.

This camshaft is ideal for street enthusiasts building or refreshing small block Chevy engines who need a dependable upgrade over original equipment without requiring specialized valve train components, custom cylinder head work, or high-RPM engine management. Whether paired with stock or mildly ported heads, carbureted or fuel-injected systems, the SBC Hyd Camshaft delivers consistent valve events compatible with standard production architecture and accessories.

COMP CAMS has established itself as a recognized manufacturer of performance camshafts for domestic engine platforms. The hydraulic flat tappet design represents the traditional foundation of American V8 performance tuning—a proven approach that remains relevant for restoration projects, weekend cruisers, and entry-level performance builds seeking to exceed factory capability without complexity. Proper installation with quality valve train components and correct valve timing is essential for optimal results.
