COMP Cams Camshaft P8 280AH-10

This COMP Cams Magnum Muscle camshaft is a hydraulic flat tappet grind designed for Pontiac 265-455 cubic inch V8 engines. It's intended for builds where a rougher idle is acceptable, typically paired with a torque converter with a 2500+ RPM stall speed and a compression ratio of 10.5:1 or higher. This camshaft is a solid option for those looking to extract more performance from their classic Pontiac V8, especially when using rear gears with a ratio of 3.73 or lower.

The Magnum Muscle series is known for its aggressive performance characteristics. This particular grind, with its 232 degrees of intake duration and 237 degrees of exhaust duration at .050 lift, is engineered to work well in engines like the 400ci Ram Air IV, or factory 345-370 HP 400 and 455ci engines from the late 60s and early 70s. It's a well-built component that can make a notable difference in how your engine performs, particularly in the mid-to-upper RPM range.

This camshaft fits a wide range of Pontiac, Buick, and Oldsmobile V8 engines from the 1950s through the early 1980s. It's important to note that this camshaft is not CARB approved and cannot be shipped to California. Ensure your engine setup, including compression and torque converter, is compatible with the specifications of this performance camshaft for optimal results.
