COMP Cams Camshaft CB XE274H-10

This COMP Cams Xtreme Energy camshaft features a 230/236 degree intake/exhaust duration split, a common choice for builders looking for improved performance in their Chevrolet Big Block engines. It’s designed for high-performance street applications, and you’ll notice a strong pull in the mid-range, especially when paired with headers and a torque converter rated for 2200 RPM or higher.

The XE274H-10 is a hydraulic flat tappet camshaft, meaning it uses a familiar and robust valvetrain design. This camshaft is well-suited for a wide range of Chevrolet vehicles originally equipped with flat tappet camshafts, including popular models like the 1967-1975 Chevrolet Impala, 1967-1972 Chevrolet Chevelle, and 1967-1974 Chevrolet Corvette. Its specific lobe profile is engineered to deliver a noticeable increase in power where you’ll feel it most during everyday driving and spirited runs.

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. For those specific applications, COMP Cams offers alternative camshafts; please contact us for assistance.
