COMP Cams Camshaft Kit CS XR270HR-11

COMP Cams is well-known for making performance parts for a wide range of vehicles, and this Xtreme 4x4 Camshaft Kit is a prime example of their expertise. This kit is designed to give your 1987 and newer Chevrolet 305 or 350 small block engine with a factory roller camshaft a noticeable boost in mid-range power. It’s a popular choice for trucks and SUVs that need more grunt for hauling or off-road use, fitting a variety of vehicles like the Chevrolet C1500 Suburban, Buick Roadmaster, and Cadillac Fleetwood.

This kit includes the CS XR270HR-11 camshaft itself, a set of hydraulic roller lifters, a timing chain set, assembly lube, decals, and installation instructions, making it a comprehensive package for your engine build. The camshaft specifications, with a 220-degree intake and 224-degree exhaust duration at .050 lift, are tuned for strong performance in the mid-RPM range. To get the most out of this camshaft, you'll want to pair it with headers, a gear ratio between 3.55 and 4.10, and a torque converter with at least a 2000 RPM stall speed. Expect a noticeable idle that signals the improved performance under the hood.

When installing this kit, remember that it's intended for OE roller camshaft-equipped engines and is not compatible with LT-1 or LS1 style engines. It's also important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for proper installation and break-in procedures to ensure optimal performance and longevity.
