What is the benefit of the nitrided surface treatment on this camshaft?

The nitriding process hardens the cam lobes, making them significantly more durable and resistant to wear. This is particularly beneficial for flat tappet camshafts, ensuring a longer service life under performance conditions.

What kind of performance gains can I expect from this camshaft?

This camshaft is designed for high-performance street use, providing a very strong mid-range power band. It works best when paired with headers and a torque converter rated for 2200 RPM or higher, offering improved acceleration and responsiveness.

Does this camshaft come with lifters or other installation hardware?

This product is for the camshaft only. It is designed to work with hydraulic flat tappet lifters, which are typically reused from the original engine or purchased separately. Always refer to the manufacturer's instructions for a complete list of recommended components.

Product Details

This COMP Cams Xtreme Energy camshaft is designed for Chevrolet Big Block engines, specifically the 396 to 454 cubic inch displacements that originally came with flat tappet camshafts. It's a hydraulic flat tappet camshaft, meaning it uses hydraulic lifters to maintain zero valve lash automatically, simplifying setup compared to solid lifter cams. The "NIT" in its name signifies that it's nitrided, a surface hardening process that makes the cam lobes more durable and resistant to wear, which is especially important for flat tappet designs.

This camshaft is built for high-performance street applications. You can expect a very strong pull in the mid-range RPMs, particularly when paired with headers and a torque converter rated for 2200 RPM or higher. The XE274H-1 grind offers a good balance for daily driving while still providing a noticeable boost in power when you need it. Its nitrided construction means it's well-built to handle the demands of performance driving.

When installing this camshaft, remember it's intended for engines originally equipped with flat tappet setups. Always refer to the manufacturer's installation instructions for proper break-in procedures and any specific requirements for your engine build.
