Product Details

This COMP Cams CS 305 H6 camshaft is a hydraulic flat tappet grind designed for drag race and oval track applications. It's intended for medium-weight cars running on longer tracks with fast corners, and it works best with a 4000+ RPM stall torque converter and 11:1 or higher compression ratio. This camshaft fits a wide range of Chevrolet Gen 1 Small Block engines, including popular options like the 350, 400, and 327 cubic inch V8s found in vehicles such as the Chevrolet Camaro, Corvette, and C10 trucks from the 1980s and early 1990s.

When you install this camshaft, you're getting a well-built component from COMP Cams, a well-known name in performance engine parts. The 253 degrees of intake and 253 degrees of exhaust duration at .050 lift are chosen to provide a strong powerband for racing conditions. It's important to note that this camshaft is designed for engines that use flat tappet lifters. If your engine was built from 1985 or later and originally came with roller lifters, this camshaft will not be a direct fit. Always confirm your engine's lifter style before ordering.
