How do I know if my Chevrolet Small Block is a flat tappet or roller engine?

You will need to remove the intake manifold or timing cover to visually inspect the camshaft and lifters. Factory roller camshafts have a different design for the lifters and pushrods compared to the flat tappet style. Many GM vehicles from the mid-1980s onward gradually transitioned to roller camshafts.

What compression ratio is recommended for this camshaft?

This camshaft is designed for engines with a compression ratio of 11:1 or higher. Using it with a lower compression ratio may result in less than optimal performance.

Does this camshaft come with a break-in oil or procedure?

The camshaft itself does not include break-in oil. It is critical to follow the manufacturer's specific break-in procedure, which typically involves running the engine at a specific RPM for a set period immediately after installation to properly seat the flat tappets and prevent premature wear.

Product Details

COMP Cams is a well-known name in performance engine parts, and this CS 282Xo-6 camshaft is built for serious power on oval tracks. It's designed for Chevrolet Gen 1 Small Block engines displacing between 327 and 358 cubic inches, especially those with 11:1 or higher compression ratios and a 2-barrel carburetor setup with good intake and exhaust flow.

This camshaft features a nitrided finish, which helps improve its durability and resistance to wear, especially important for flat tappet designs. The lobe separation is set at 112 degrees, and the intake and exhaust duration are 252 and 254 degrees respectively at .050 inch lift. This profile is intended for engines that see a lot of use, like those in racing applications, and it works well with a 2-barrel carburetor and good breathing cylinder heads. Keep in mind that this camshaft is for flat tappet engines, so you'll need to confirm your block doesn't have a factory roller setup, which became common in the mid-80s and later for many GM vehicles.

This camshaft fits a wide range of Chevrolet Gen 1 Small Block engines, including popular models like the Camaro, Corvette, Caprice, and C10 trucks from various years. It's important to verify your specific engine's configuration, as some earlier 265 cubic inch engines may require an oiling groove on the fifth cam journal. Always refer to the manufacturer's installation instructions for proper setup and break-in procedures.
