COMP Cams Camshaft Kit CS 306S

If you're looking to give your Chevrolet Gen 1 Small Block engine a serious performance boost for street and strip use, this COMP Cams CS 306S Camshaft Kit is a solid choice. This kit is designed for engines built for speed, typically paired with a 3500+ RPM stall converter, 10.5:1 compression, low-gear ratios, and aftermarket headers and intake. Expect a noticeable, racy idle that signals this engine means business.

This isn't just a camshaft; it's a complete package to ensure a smooth and effective upgrade. Inside this K-Kit, you'll find the CS 306S camshaft itself, along with matching lifters, valve springs, retainers, valve locks, and valve stem seals. To make installation easier and ensure proper break-in, it also includes a timing chain set and assembly lube, as well as decals and instructions. This comprehensive approach helps ensure all components work together harmoniously for improved performance.

This kit fits a wide range of Chevrolet Gen 1 Small Block engines, including popular displacements like the 262, 283, 305, 327, 350, and 400. It's important to verify your specific engine is a flat tappet design, as factory roller camshafts were gradually introduced from the mid-80s onward, especially in performance models like Camaros and Corvettes. Removing the intake or timing cover is the best way to confirm. This kit is not compatible with LT1/LT4 engines or LS-based V8s.
