COMP Cams Camshaft CB XR294HR-10

COMP Cams is well-known for making performance valvetrain components, and this Xtreme Energy hydraulic roller camshaft is a prime example of their work. This camshaft, part number 11-443-8, is designed for Chevrolet Big Block engines like the 396, 427, and 454, and it fits a wide range of vehicles from 1967 through 1993, including popular models like the Chevrolet C10 Pickup, Camaro, and Impala. It's a great choice if you're looking to get more out of your street or strip machine.

This XR294HR-10 camshaft features a 242-degree intake duration and a 248-degree exhaust duration, both at 0.050 inch lift, with a 110-degree lobe separation angle. It's built for engines with 10:1 or higher compression ratios, and it works best when paired with a torque converter with a 3000+ RPM stall speed, along with intake and header upgrades. The hydraulic roller design means it's designed for less friction and better performance compared to flat tappet cams, and it's well-built to handle the demands of spirited driving and racing applications.

When installing this camshaft, remember that it's intended for engines originally equipped with flat tappet camshafts. If your 1965-1966 396 Big Block has an oiling groove in the rear journal, this specific part number will not fit, and you'll need to contact COMP Cams directly for a different option. This camshaft is not CARB approved and cannot be shipped to California.
