COMP Cams Cam & Lifter Kit CS 280R

This COMP Cams Magnum 236/236 solid roller camshaft and lifter kit is built for performance applications on Chevrolet Gen 1 Small Block engines. The camshaft features a 236-degree intake and 236-degree exhaust duration at .050 lift, designed to provide a noticeable, choppy idle characteristic that signals serious street/strip intent. To make the most of this camshaft's performance potential, it's recommended to pair it with a torque converter rated at 2500 RPM or higher and a good set of headers. This kit is intended for builds targeting around 9.5:1 compression, balancing power with pump gas compatibility.

Included in this kit are the solid roller camshaft, matching solid roller lifters, assembly lube to ensure proper break-in, decals, and installation instructions. This setup is designed for engines that originally came with a flat tappet camshaft. It's important to verify your engine block's configuration, as GM gradually introduced roller camshafts into Small Blocks starting in the mid-1980s. While many performance engines from the 50s through the early 80s are direct fits, later models may require checking for a factory roller setup or a specific oiling groove on the 5th cam journal for 1955-1957 265 engines.

This kit is a solid option for enthusiasts looking to significantly upgrade their Chevrolet Small Block's performance profile. It's crucial to confirm fitment for your specific vehicle, as this kit is not compatible with LT1/LT4 engines or factory roller Small Blocks from 1985 and newer, nor any LS-based engines. For those with a compatible flat tappet block, this kit offers a pathway to improved performance and that classic aggressive idle.
