COMP Cams Camshaft CS 280H-R10

COMP Cams is well-known for performance engine components, and their Magnum line of camshafts is a popular choice for builders looking to get more out of their engines. This CS 280H-R10 camshaft is a hydraulic roller grind designed for Chevrolet Small Block engines from 1958 through 2002, covering a wide range of displacements from 262 to 400 cubic inches. It's intended for limited high-performance street applications, meaning you'll need to pair it with other upgraded parts to really make it shine.

To get the most out of this camshaft, you'll need an aftermarket intake manifold, headers, a torque converter with at least a 2200 RPM stall speed, and rear end gears in the 3.40 to 4.10 range. Expect a mild, rough idle with this camshaft. It also requires specific installation components like a thrust button and wear plate, and a suitable timing cover that incorporates these features. For optimal performance and to prevent premature wear, it's crucial to use a high-pressure, high-volume fuel pump with a bronze-tipped pushrod and aftermarket valve springs. Additionally, COMP Cams strongly advises using a melanized or nitrided distributor gear; using a standard cast or steel gear without similar surface treatments will void your warranty.

This camshaft fits a wide variety of Chevrolet Small Block applications, including popular models like the Chevrolet Camaro, Corvette, and C10 trucks. It's important to verify your specific engine block's configuration, as GM transitioned to roller lifter provisions in the late 80s. If your block has the provisions but lacks roller components, COMP Cams offers kits to convert it. This camshaft is not compatible with LT1/LT4 engines or LS-based engines.
