COMP Cams Cam & Lifter Kit CS 280H-R10

When you're looking to get more out of your Chevrolet Small Block Gen 1 engine, this COMP Cams Magnum hydraulic roller cam and lifter kit is a solid option. What you get in the box is everything you need to get started: the camshaft itself, a set of lifters, assembly lube to get everything properly coated from the start, and some decals to show off your new setup. This kit is designed for limited high-performance street use, meaning it’s built to handle the demands of daily driving while still offering a noticeable bump in power.

This kit features a 224/224 duration camshaft, which is a popular choice for street builds. It’s designed to work well with aftermarket intake manifolds, headers, a torque converter with a stall speed of 2200 RPM or higher, and rear-end gears in the 3.40 to 4.10 range. You can expect a mild, rough idle with this cam, which is characteristic of performance camshafts and lets you know the engine is breathing better. It’s important to confirm your specific engine is a flat tappet block, as this kit is not compatible with factory roller small blocks from 1985 and newer, or LT1/LT4 engines. Some engines from the mid-80s onward gradually adopted roller cams, so a quick check by removing the intake or timing cover will confirm compatibility.

For engines that require it, like the 1955-1957 Chevrolet 265, ensure there's a groove on the 5th cam journal for proper oiling. This kit is a significant upgrade for your engine's performance, and while it’s designed for street use, it’s best paired with supporting modifications to truly unlock its potential.
