COMP Cams Camshaft Kit CS XR280HR-11

If you're looking to build a performance Chevrolet Small Block Gen 1 engine that needs strong mid-range power, this COMP Cams CS XR280HR-11 hydraulic roller camshaft kit is a solid option. This kit is designed for engines like the 350, 327, or 400 cubic inch small blocks, offering a notable increase in power through the RPM range where you'll spend most of your time driving. It's important to note that this camshaft is intended for engines that originally used a flat tappet camshaft; it is not compatible with factory roller camshafts found in many 1985 and newer small blocks, or the LS-based engines. You'll need to confirm your specific engine's setup to ensure proper fitment.

This is a complete kit, meaning it includes everything you need to get the camshaft installed and running. You get the camshaft itself, a set of hydraulic roller lifters, valve springs, retainers, valve locks, and valve stem seals. To ensure proper timing, a timing chain set is also included, along with assembly lube and installation instructions. For this camshaft to perform at its best, you'll want to pair it with headers, a gear ratio in the 3.73 to 4.10 range, and a torque converter with at least a 2500 RPM stall speed. Expect a rougher idle characteristic with this performance grind.

This kit is a comprehensive solution for enthusiasts looking to significantly upgrade their engine's performance. It's built for a wide range of Chevrolet Small Block Gen 1 applications, including many trucks and older performance cars. Remember to verify your engine's original camshaft type before purchasing, as this kit is designed for the transition from flat tappet to roller technology.
