COMP Cams Camshaft CS 304A-R6 .900 Bc

If you're building a late model Chevrolet Small Block for oval track racing, especially for longer tracks where consistent power delivery is key, this COMP Cams CS 304A-R6 camshaft is a solid option. It's a solid roller camshaft with a duration of 268 degrees on the intake and 272 degrees on the exhaust, designed to work with .900 lift valve springs. This camshaft is intended for engines that are not factory roller blocks, typically pre-1985 models, though some trucks and SUVs retained flat tappet cams into the mid-90s. It's important to verify your block's configuration before installation.

This camshaft is built for performance in demanding racing environments. The solid roller design allows for higher lift and faster valve action compared to hydraulic lifters, which is crucial for maximizing power output in high-RPM situations common in oval track racing. COMP Cams is well-known for producing reliable engine components, and this camshaft is no exception, offering a well-built part designed to withstand the rigors of competition.

It's important to note that this camshaft is not CARB approved and cannot be shipped to California. Also, 1955-1957 Chevrolet engines require a specific oiling groove on the rear journal, and this particular part number does not fit those early blocks. If your engine requires that groove, you'll need to contact us for a specific application. For other Small Block Chevy applications, it fits a wide range of displacements from 262 up to 400 cubic inches, excluding factory roller blocks and LS-based engines.
