SBC Hyd. Roller Camshaft

The SBC hydraulic roller camshaft by HOWARDS RACING COMPONENTS is engineered for small-block Chevrolet engines seeking reliable performance gains and extended valve train life. This precision-ground cam profile delivers improved airflow efficiency across the RPM band, making it an ideal upgrade for street performance, mild racing, and rebuilt engine applications. Hydraulic roller cams eliminate the wear patterns associated with flat-tappet designs, reducing friction and engine stress while maintaining factory-compatible valvetrain geometry for straightforward installation.

Hydraulic roller camshafts use precision roller lifters instead of conventional flat followers, significantly reducing parasitic friction loss and enabling aggressive lift and duration without punishing the valvetrain. The roller design allows tighter tolerances and more predictable valve timing control, translating to improved combustion efficiency and throttle response. HOWARDS RACING COMPONENTS profiles are computer-optimized for duration, lift, and lobe separation angle (LSA) to maximize power output while preserving streetability and fuel efficiency on standard fuel and ignition systems.

This camshaft is suited for enthusiasts rebuilding 262 to 400 cubic-inch SBC engines or upgrading tired stock units without expensive head or induction modifications. It pairs seamlessly with factory or aftermarket hydraulic roller lifter sets, compatible pushrods, and standard small-block Chevy timing components—no exotic oil systems or custom machine work required. Proper installation requires checking valve-to-piston clearance and setting initial valve lash per HOWARDS specifications to ensure optimal performance and long component life.
