COMP Cams Camshaft CB 270H-10

With a camshaft duration of 224 degrees on both the intake and exhaust, this COMP Cams Magnum series camshaft is a well-built option for Chevrolet Big Block engines. It's designed to offer noticeable performance gains over stock, especially in the higher RPM range, without putting undue stress on your valve train components. This makes it a solid choice for street machines that see regular use, and it works well with stock torque converters, though a higher stall converter around 1800 RPM is recommended for 396 cubic inch engines paired with 3.55-3.73 gears. It also pairs nicely with headers for improved exhaust flow. While it provides a good bump in power, expect a slightly rough idle, which is typical for a camshaft of this nature. This camshaft is best suited for engines with a static compression ratio of 9.5:1 or higher and works well with mild ratio rocker arms and traditional performance valve springs.

This camshaft fits a wide range of Chevrolet vehicles, including popular models like the 1967-1973 Chevelle, 1967-1972 Camaro, and 1967-1974 Corvette, among many others originally equipped with flat tappet camshafts. It's a great way to wake up your Big Block engine for street performance applications.
