COMP Cams Camshaft CB XM 288H-12

This COMP Cams Xtreme Marine camshaft is a hydraulic flat tappet camshaft designed for Chevrolet Big Block engines, specifically the 396 to 454 cubic inch displacements. It's intended for performance applications and works well with headers and a compression ratio of 9.5:1 or higher. This camshaft is suitable for a wide range of Chevrolet vehicles originally equipped with flat tappet camshafts, including models like the C10 Pickup, Impala, and Camaro from various years.

The XM288H grind offers a 244/254 degree intake/exhaust duration at .050 inch lift, providing a noticeable bump in performance over stock. It's built for engines that will see spirited use, and it's important to note that this specific camshaft is not CARB approved and cannot be shipped to California. For 1965-1966 396 Big Block engines with an oiling groove in the rear journal, this particular camshaft will not fit; a different part number would be required.
