COMP Cams Cam & Lifter Kit CS 270S

This COMP Cams CS 270S kit centers around a solid flat tappet camshaft designed for Chevrolet Gen 1 Small Block engines. The camshaft features a 224/224 duration at .050 inch lift, a common specification that offers a noticeable idle and improved street performance without requiring extensive modifications to your setup. It's built to work with a stock torque converter, though it performs best with one rated around 2000 RPM or higher, and benefits from lower rear-end gears to help keep the engine in its power band.

Included in this kit are the matching solid lifters, assembly lube to ensure proper break-in, and decals. This setup is intended for engines that originally came with a flat tappet camshaft. It's important to verify your engine's configuration, as GM began phasing in roller camshafts in the mid-1980s, particularly in performance models like Camaros and Corvettes, though trucks and SUVs sometimes retained flat tappet cams into the mid-1990s. Removing the intake manifold or timing cover is the surest way to confirm if your block is factory roller or flat tappet.

This kit is a solid option for enthusiasts looking to upgrade their classic Chevrolet V8. While streetable, expect a more pronounced idle compared to stock. It's designed to fit a wide range of Chevrolet Small Block applications, including popular engines like the 350, 327, and 400 cubic inch variants, but does not fit LT1, LT4, or LS-based engines.
