COMP Cams Camshaft CB Nx298HR-13

This COMP Cams Nitrous HP Hydraulic Roller Camshaft, part number 11-414-8, is built with a specific lobe separation angle of 113 degrees. This design choice is crucial for maximizing performance when paired with nitrous oxide systems or large superchargers, aiming for over 200 horsepower gains. It's intended for Chevrolet Big Block engines, specifically the 396 to 454 cubic inch displacements, and is designed to work with hydraulic roller lifters for improved durability and reduced friction compared to flat tappet designs.

Engineered for serious power, this camshaft is optimized for use with a Melanized or Nitrided distributor gear to ensure proper function and longevity; using cast or steel gears without these surface treatments will void the warranty. It requires a compression ratio of 9.5:1 or higher and a torque converter with a stall speed of 2800 RPM or more to effectively utilize its aggressive profile. This camshaft is a popular choice for builds targeting significant horsepower increases, whether through nitrous injection or a 671 series or larger supercharger.

This camshaft fits a wide range of Chevrolet vehicles originally equipped with flat tappet camshafts, including models like the 1967-1975 Chevrolet Bel Air, 1967-1972 Chevrolet Camaro, and 1967-1974 Chevrolet Corvette. It is important to note that this camshaft is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper distributor gear selection and other critical setup details to ensure optimal performance and warranty coverage.
