How do I know if my Chevrolet Small Block has a flat tappet or roller camshaft?

For Chevrolet Gen 1 Small Blocks, you'll need to inspect the valvetrain. Engines from 1985 and newer often came with factory roller cams, though this varied by model and production date. Removing the intake manifold or timing cover is the most reliable way to confirm if your engine uses a flat tappet or roller camshaft.

What compression ratio is recommended for this camshaft?

This COMP Cams CS 282Xos-6 camshaft is designed for engines with a 12:1 or higher compression ratio. This allows for optimal performance gains when paired with the camshaft's specifications.

Does this camshaft come with lifters or other valvetrain components?

This product is for the camshaft only. Lifters, pushrods, valve springs, and other valvetrain components are sold separately and should be chosen to match the camshaft's specifications for optimal performance and reliability.

Product Details

COMP Cams is a well-known name in performance engine parts, and this CS 282Xos-6 solid flat camshaft is built for serious power. It's designed for Chevrolet Gen 1 Small Block engines ranging from 327 to 358 cubic inches, especially those with a 12:1 or higher compression ratio and a 4-barrel carburetor with good intake and exhaust flow. This camshaft is nitrided, a process that hardens the surface to resist wear and improve durability over time, which is a notable benefit for a flat tappet design.

This camshaft is intended for applications where tight valve lash is preferred, typically 1/4 to 3/8 of an inch. It's a popular choice for oval track racing and performance street builds where maximum engine output is the goal. While it fits a wide range of Chevrolet Gen 1 Small Blocks, it's important to confirm your engine uses a flat tappet valvetrain, as many later models (from 1985 onward) switched to factory roller cams. Removing the intake manifold or timing cover is the best way to be sure.
