COMP Cams Camshaft CB 326A-R14

This COMP Cams CB 326A-R14 solid roller camshaft is designed for Chevrolet Big Block engines, specifically the 396 to 454 cubic inch displacements. It's built for drag racing applications and features a 286-degree intake duration and 310-degree exhaust duration with a .050 inch lift of 246 degrees on the intake and 254 degrees on the exhaust. This camshaft requires the use of solid roller lifters, roller rocker arms, and appropriate valve springs, which are not included with this part. It's important to note that this camshaft is not CARB approved and cannot be shipped to California. It is intended for engines originally equipped with flat tappet camshafts, meaning you'll need to upgrade to a full solid roller valvetrain to use it.

The CB 326A-R14 is a well-built camshaft that offers a significant performance upgrade for your Big Block Chevrolet. Its aggressive profile is optimized for high-RPM power, making it a popular choice for drag strip use where maximum acceleration is key. The solid roller design allows for higher lift and faster valve events compared to hydraulic or flat tappet cams, contributing to improved airflow and power output. When installing this camshaft, ensure your engine's valvetrain components are compatible and that you follow the manufacturer's recommended break-in procedure to ensure proper seating and longevity.

This camshaft fits a wide range of Chevrolet vehicles equipped with the 396-454 Big Block engine, including models like the Chevrolet Impala, Chevelle, and Corvette from the late 1960s through the mid-1970s. It's a substantial upgrade for enthusiasts looking to extract more power from their classic Bowtie big-block. Remember to verify all other valvetrain components, such as lifters, pushrods, and valve springs, are rated for solid roller use and the specific lift and duration of this camshaft.
