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

The nitrided finish hardens the surface of the camshaft lobes and journals. This makes it more resistant to wear, which is particularly beneficial for flat tappet camshafts and helps ensure a longer service life.

What kind of idle can I expect with the COMP Cams XE284H-1 camshaft?

This camshaft is designed for street/strip performance and is known for a rough idle. It's intended for enthusiasts who prioritize performance and are comfortable with a less refined idle quality.

What other components are recommended when installing this camshaft?

For optimal performance and durability, COMP Cams recommends using this camshaft with a 2800+ stall torque converter and an engine compression ratio of 9.5:1 or higher. It's also important to ensure your engine originally used a flat tappet camshaft.

Product Details

COMP Cams is well-known for making performance engine parts, and their Xtreme Energy line is a popular choice for folks looking to get more out of their engines. This particular camshaft, the XE284H-1, is a hydraulic flat tappet grind designed for Chevrolet Big Block engines like the 396 and 454. It’s built for street/strip applications, meaning it’ll perform well on the road and at the drag strip, but expect a rougher idle and it’s best paired with a 2800+ stall torque converter and at least 9.5:1 compression.

What sets this cam apart is its nitrided finish. This process hardens the surface of the camshaft lobes and journals, making it more resistant to wear, especially important with flat tappet designs. This nitriding helps ensure a longer service life and consistent performance over time. It’s a well-built piece that’s designed to handle the demands of a performance engine build.

This camshaft fits a wide range of Chevrolet vehicles originally equipped with flat tappet camshafts, including models like the Chevrolet C10 Pickup, Impala, and Chevelle from the late 60s through the mid-70s. Make sure your engine is set up for this type of camshaft, especially regarding compression and stall speed, to get the most out of it.
