What is the benefit of a nitrided camshaft?

The nitriding process hardens the surface of the camshaft, which significantly improves its wear resistance and durability. This is especially beneficial for performance engines that experience higher stresses and loads.

What compression ratio and exhaust system are recommended for this camshaft?

This camshaft is recommended for engines with a compression ratio of 9.5:1 or higher. It also requires the use of headers to achieve optimal performance gains.

Can this camshaft be used in California?

No, this camshaft is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

This COMP Cams Nitrided Camshaft is designed for Chevrolet Big Block engines, specifically the 396 to 454 cubic inch displacements originally equipped with flat tappet camshafts. You'll receive the camshaft itself, ready for installation into performance applications. This camshaft is nitrided for improved durability and wear resistance, a common upgrade for engines running 9.5:1 or higher compression ratios and requiring headers.

The 244/254 duration at 0.050 inch lift profile is a popular choice for performance builds, offering a noticeable increase in power and torque over stock camshafts. Its hydraulic flat tappet design means it's compatible with many factory valvetrain components, though it's intended for performance use where headers are already part of the setup. The nitriding process hardens the surface of the camshaft, helping it withstand the rigors of higher performance use and extending its service life.

This camshaft is intended for performance applications and is not CARB approved, meaning it cannot be shipped to California. Ensure your engine setup, including compression ratio and exhaust, is suitable for this type of performance camshaft.
