What is the benefit of a nitrided camshaft?

The nitriding process hardens the surface of the camshaft, making it significantly more resistant to wear and friction. This leads to a longer lifespan for the camshaft and the associated valvetrain components.

How can I tell if my engine has a flat tappet or roller camshaft?

The easiest way to confirm is by removing the intake manifold or timing cover. Factory roller camshafts have a distinct design for the lifter and pushrod system, whereas flat tappet systems are more straightforward. Many GM vehicles from the mid-80s onward began phasing in roller cams.

What other parts are typically recommended when installing a new camshaft?

When installing a new camshaft, it's common practice to also replace the lifters, valve springs, and pushrods to ensure optimal performance and reliability. A new timing set is also highly recommended.

Product Details

This COMP Cams camshaft features a nitrided finish, a hardening process that makes the surface exceptionally durable and resistant to wear. It's designed for Chevrolet Gen 1 Small Block engines, specifically for street/strip applications where you're looking for improved performance beyond stock. The 240/246 degrees of intake/exhaust duration at .050 lift means this cam will give you a noticeable, rougher idle and really wakes up when paired with headers and performance gearing.

This camshaft is a hydraulic flat tappet design, meaning it uses hydraulic lifters to maintain zero valve lash. It's built to handle higher RPMs, suggesting a stall speed of 2800 RPM or more for automatic transmissions. While it's a popular choice for performance builds, remember that it's intended for engines that use flat tappet lifters, not factory roller setups found in many later model Small Blocks. Always confirm your engine's configuration before installation.

This cam fits a wide range of Chevrolet Gen 1 Small Block engines, including popular displacements like the 350, 400, and 327. It's a solid option for enthusiasts looking to add more power and a more aggressive feel to their classic Chevy or GM vehicle, such as a 1980s Camaro, a 1990s Caprice, or a C10 pickup.
