Product Details

This COMP Cams XR270H-R12 camshaft kit is built around a hydraulic roller camshaft with a 218/224 degree intake/exhaust duration. This specific grind is a popular choice for pleasure boats, offering a good idle and improved performance over stock. It’s designed for Chevrolet Big Block engines originally equipped with flat tappet camshafts, and it fits a wide range of vehicles including the Chevrolet Impala, Chevelle, and Corvette from the late 60s through the mid-70s.

When you choose this K-Kit, you're getting a complete package to ensure a smooth and successful camshaft swap. Inside the box, you'll find the camshaft itself, a set of hydraulic roller lifters, valve springs, retainers, valve locks, and valve stem seals. To make sure the timing is spot on, a timing chain set is included, along with assembly lube and decals. This comprehensive approach means you won't be scrambling for extra parts during installation, making the job more straightforward.

The XR270H-R12 profile is tuned for a good idle and is well-suited for applications where a reliable and responsive powerband is desired. While this kit is designed for performance, it maintains a manageable idle characteristic, making it a solid option for various builds. Always refer to the included instructions for detailed installation procedures and specifications.
