COMP Cams Camshaft CB 266H-R12

This is the COMP Cams CB 266H-R12 hydraulic roller camshaft, designed for Chevrolet Big Block engines like the 396, 427, and 454 cubic inch displacements. If you're looking to wake up your classic Chevy or a modern build based on these robust engines, this camshaft is a solid option for computer-controlled applications. It's built to replace your original flat tappet camshaft with a more efficient hydraulic roller setup, which generally means less friction and better performance over time.

The CB 266H-R12 features a 210-degree intake duration and a 220-degree exhaust duration at .050 inch lift, with a 112-degree lobe separation angle. This specific grind is well-suited for street performance, offering a noticeable improvement in throttle response and power band without being overly aggressive for daily driving. The hydraulic roller design means you won't need to worry about the frequent oil changes and potential wear issues associated with traditional flat tappet cams. It's a well-built component that aims to provide a strong, reliable performance upgrade for your Big Block.

It's important to note that this camshaft is designed for engines originally equipped with flat tappet camshafts and requires the appropriate valvetrain components to work correctly. Also, this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and break-in procedures to ensure optimal performance and longevity.
