SBC Hydraulic Camshaft 305H-6

The SBC Hydraulic Camshaft 305H-6 from COMP CAMS is a precision-engineered performance upgrade designed for small-block Chevrolet engines seeking reliable hydraulic valve actuation with improved efficiency. Built for street and mild performance applications, this hydraulic camshaft serves builders and mechanics who demand consistent valve timing without the complexity of solid roller or mechanical systems. Whether you're refreshing a tired 305 or upgrading a budget-conscious build, the 305H-6 delivers the durability and predictable power curve that makes hydraulic cam profiles the industry standard for daily drivers and weekend cruisers.

This camshaft utilizes precision-ground lobes and a hardened core to resist wear across thousands of miles and heat cycles. The hydraulic lifter design automatically maintains zero lash, eliminating the need for manual valve adjustment and reducing noise while improving component longevity. The 305H-6 profile balances intake and exhaust duration to optimize cylinder-filling efficiency while keeping peak RPM practical for stock or mildly modified cylinder heads.

Ideal for 305 cubic-inch small-block Chevrolet engines in trucks, muscle cars, and classic hot rods, the SBC Hydraulic Camshaft 305H-6 pairs seamlessly with hydraulic lifter-equipped blocks and standard timing chains. This camshaft is compatible with factory or aftermarket intake manifolds and carburetors common to SBC platforms, making it a versatile choice for performance enthusiasts.
