COMP Cams Nitrided Camshaft CS 286Xo-8

If you're building a late-model stock oval track engine for a 1/4 to 3/8 mile track, especially a 358 cubic inch with limited intake and carb, this COMP Cams Nitrided Camshaft is a solid option. This camshaft is designed for Chevrolet Small Block engines, specifically those with flat tappet configurations. It's a popular choice for racers looking to get the most out of their engine within specific class rules.

The 'nitrided' in the name refers to a surface hardening process applied to the cam lobes. This treatment significantly improves wear resistance, which is crucial for flat tappet camshafts that rely on direct metal-to-metal contact for lubrication. This means you can expect a longer service life and more consistent performance over time, even under the demanding conditions of racing. The 256/258 degree duration at 0.050 inch lift provides a good balance for this type of application, offering improved performance without being overly aggressive for restricted classes.

This camshaft fits a wide range of Chevrolet Gen 1 Small Block engines, including popular displacements like the 350, 327, and 305. However, it's important to verify your engine's configuration, as it does not fit factory roller camshaft engines from 1985 and newer, nor does it fit any LS-based engines. Always consult your vehicle's service manual or inspect your engine to confirm if you have a flat tappet or roller setup before ordering.
