What is the main benefit of the nitrided finish on this camshaft?

The nitrided finish on this camshaft helps to increase its durability and wear resistance. This is particularly beneficial for flat tappet camshafts, ensuring a longer service life under demanding conditions.

How do I know if my Chevrolet Small Block engine uses a flat tappet camshaft?

Many Chevrolet Small Blocks from the mid-80s onward gradually switched to roller camshafts. To confirm, you may need to remove the intake manifold or timing cover to inspect the lifter and camshaft design. Trucks and SUVs often retained flat tappet cams later than cars.

What kind of stall speed converter is recommended for this camshaft?

This camshaft is designed for strong mid-range torque and is recommended for use with a torque converter that has a stall speed of 2200 RPM or higher. This helps to keep the engine in its powerband during acceleration.

Product Details

COMP Cams has a solid reputation for making performance engine components, and this Xtreme Energy Nitrided Camshaft is a great example of their work for Chevrolet Small Block engines. If you're looking to get more out of your engine, this camshaft is designed to deliver a noticeable boost in mid-range torque and throttle response, making it feel much more lively when you're on the gas. It's built for engines that can handle a 2200+ RPM stall speed, so it's a good match for performance-oriented builds.

This camshaft features a nitrided finish, which helps to increase its durability and wear resistance, especially important for flat tappet designs. The grind profile, with intake and exhaust durations of 230 and 236 degrees respectively, is specifically tuned to wake up the mid-range powerband. This means you'll feel a strong pull from around 2200 RPM up to where the engine typically shifts gears, making it ideal for street performance applications. It fits a wide range of Chevrolet GEN 1 Small Block engines, including popular displacements like the 350, 400, and 283, but it's important to verify your specific engine uses a flat tappet setup, as many later models switched to roller cams.
