COMP Cams Camshaft Kit CS XR270HR-11

COMP Cams has a long history of making serious performance parts for engines, and this K-KIT camshaft kit is a prime example of their work. If you're building a Chevrolet Small Block Gen 1 engine and want to improve its mid-range power, this kit is designed for that goal. It's a hydraulic roller camshaft, which generally offers better performance and less wear than older flat tappet designs. You'll notice a more aggressive idle with this cam, and it's built to work best with headers, a gear ratio between 3.55 and 4.10, and a torque converter with a stall speed of 2000 RPM or higher.

This isn't just a camshaft; it's a complete K-KIT, meaning it comes with everything you need to get the job done right. Inside the box, you'll find the camshaft itself, hydraulic roller lifters, valve springs, retainers, valve locks, and valve stem seals. To make sure your timing is spot on, a timing chain set is also included, along with assembly lube and decals. This comprehensive package helps ensure a smooth installation and reliable performance. This kit fits a wide range of Chevrolet Small Block Gen 1 engines, including popular models like the Chevrolet C10, Camaro, and Caprice, among many others.

Because this is a performance camshaft kit, it's important to note that it's not CARB approved and cannot be shipped to California. Also, remember that factory roller camshafts were gradually introduced in many Small Block Chevys starting in the mid-80s. You'll need to check your specific engine to confirm if it's a factory roller or a flat tappet design before installation. For 1955-1957 Chevrolet 265 engines, a specific oiling groove modification might be needed on the 5th cam journal.
