COMP Cams Camshaft CS 281Tkb-R6

Starting with the 253/262 degree duration specs, this COMP Cams Solid Roller Camshaft is built for Chevrolet Small Block engines, specifically targeting the 355-377 cubic inch Sportsman and Late Model oval track applications. It's designed to deliver strong torque, especially when working within gear rules, making it a solid choice for competitive racing where consistent power delivery is key. This camshaft is optimized for use with Melanized or Nitrided distributor gears; using cast or steel gears without these surface treatments will void the warranty and return policy, so be sure to check your setup.

This camshaft fits a wide range of Chevrolet Gen 1 Small Block engines, including popular displacements like the 350 and 400, as well as smaller options like the 262 and 305. However, it's important to note that it does not fit LT1/LT4 engines or factory roller small blocks from 1985 and newer, as GM gradually introduced roller camshafts into production vehicles. For 1955-1957 models, a specific oiling groove is required on the rear journal, and this particular part number does not include it; contact us if your early model requires this feature. Ensure your engine block is a flat tappet design or confirm compatibility before installation.

When installing this camshaft, it's crucial to use the correct distributor gear to ensure longevity and maintain your warranty. Melanized or nitrided gears are recommended to handle the forces involved with a solid roller setup. This camshaft is a significant upgrade for performance-oriented builds, offering a noticeable improvement in power and torque for racing applications.
