SBC Hydraulic Cam 151H

The COMP CAMS SBC Hydraulic Cam 151H is a factory muscle hydraulic flat tappet camshaft engineered for small block Chevy engines seeking reliable street performance and classic horsepower gains. Designed for enthusiasts and rebuilders who value stock-style valvetrain simplicity without sacrificing power delivery, this cam leverages proven hydraulic technology that requires no complex adjustments or specialized setup procedures. Whether you're restoring a vintage muscle car or refreshing a street engine with period-correct performance, the SBC Hydraulic Cam 151H delivers the familiar aggression that made small block Chevys legendary.

This hydraulic flat tappet camshaft features symmetrical 0.447-inch lift on both intake and exhaust with a 342-degree duration spec and 114-degree lobe separation angle, producing peak power between 1800 and 5800 RPM. The hydraulic design automatically compensates for thermal expansion and valve lash, eliminating manual adjuster maintenance while maintaining consistent valve timing across varying engine temperatures and loads. Flat tappet lobes and hydraulic lifters provide a durable, cost-effective arrangement ideal for carbureted or early fuel-injected small blocks, with the proven COMP CAMS engineering ensuring proper lobe geometry and lifter compatibility throughout the RPM range.

The SBC Hydraulic Cam 151H suits small block Chevy rebuilds from 265 to 400 cubic inches, making it ideal for street cruisers, mild performance builds, and restoration projects prioritizing reliability over extreme RPM capability. Installation requires standard small block Chevy cam bearing saddles and hydraulic lifters; verify your engine block, timing cover, and lifter bore condition before ordering. This single camshaft is sold individually—ensure you have a complete cam installation kit including new lifters, timing chain, and gaskets for optimal results and longevity.
