Product Details

COMP Cams has a long history of making solid performance parts for engines, and this CS 274L322 S7 solid flat camshaft is a great example for your Chevrolet Small Block. It's designed for builds where you might be running restricted carburetors or for longer track use, offering a .322" lobe lift. This camshaft is built for Chevrolet GEN 1 Small Blocks, fitting a wide range of engines like the 265, 350, and 400 cubic inch V8s. You'll find it fits many GM vehicles from the early 80s through the mid-90s, including popular models like the Chevrolet C10, Camaro, and Caprice. Just be sure to check if your specific engine uses a factory roller camshaft, as this flat tappet design is not compatible with those later models. Also, be aware that early 1955-1957 Chevrolet 265 engines require a specific oiling groove on the rear journal that this particular camshaft does not have.

This camshaft features a 248 degrees of intake duration and 252 degrees of exhaust duration at .050 lift, which is a popular setup for street performance and mild racing applications. It's designed to work well with stock or aftermarket rocker arms, especially those with a .480" or .500" lift limit. When installing, remember that this is a solid lifter camshaft, which typically requires more frequent adjustment of valve lash compared to hydraulic lifters to maintain optimal performance and engine health. It's a well-built component that can make a notable difference in how your engine breathes and performs.
