COMP Cams Camshaft CB 270H-R10

COMP Cams is well-known for its performance camshafts and valvetrain components, and this Magnum 215/215 Hydraulic Roller Camshaft is a solid option for anyone looking to improve their Chevrolet Big Block engine. This camshaft is designed for daily driven street machines and works well with stock torque converters, making it a practical choice for a wide range of vehicles. It particularly likes headers, which will help it breathe better and perform at its best.

This camshaft features a 215/215 degree duration at 0.050 inch lift, making it a noticeable upgrade over stock flat tappet cams. For 396 cubic inch engines, COMP Cams recommends a gear ratio of 3.55 to 3.73 or numerically higher to get the most out of this cam. You can expect a slightly rougher idle than a stock camshaft, which is typical for performance grinds like this one. It's built for Chevrolet Big Block engines originally equipped with flat tappet camshafts, covering a broad range of applications from 1967 through 1993, including popular models like the Chevrolet Impala, Chevelle, and C10 Pickup.

When installing this camshaft, it's important to note that it is not CARB approved and cannot be shipped to California. 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 solutions. Ensure you have the correct valvetrain components, such as lifters and valve springs, to match this hydraulic roller camshaft for optimal performance and reliability.
