COMP Cams Camshaft Kit CS 270H

This is the COMP Cams CS 270H Hydraulic Flat Cam Kit, part number K12-211-2. It's designed for Chevrolet Gen 1 Small Block engines, covering a wide range of displacements from 262 all the way up to 400 cubic inches. This kit is a significant performance upgrade, best suited for applications using a stock torque converter, though it really shines with a 2000+ RPM stall converter and lower rear-end gears. Expect a mild, rough idle with this camshaft.

When you're looking to get more out of your classic Chevy V8, a camshaft upgrade is one of the most effective ways to change its personality and powerband. This kit takes the guesswork out of selecting compatible parts by bundling everything you need for the installation. Inside the box, you'll find the CS 270H camshaft itself, a set of hydraulic lifters, valve springs, retainers, valve locks, valve stem seals, and a timing chain set. It also includes assembly lube for the flat tappet components and installation instructions. This is a well-built kit designed to give your engine a noticeable boost in performance.

It's important to confirm your specific engine uses a flat tappet camshaft, as many later model Small Blocks (from 1985 and newer) were equipped with factory roller camshafts. You can usually tell by removing the intake manifold or timing cover. This kit is not compatible with LT1/LT4 engines or any LS-based V8s. For 1955-1957 Chevrolet 265 engines, a specific oiling groove on the 5th cam journal is required; please contact us if your engine falls into this category.
