COMP Cams Camshaft CS 287Tkn-R7 .900Bc

Starting with its .900 inch lift solid roller design, the COMP Cams CS 287Tkn-R7 camshaft is built for serious performance in Chevrolet Small Block engines, particularly those in the 383-415 cubic inch range used in oval track racing like IMCA and Late Models. This camshaft is engineered to deliver strong torque, making it a valuable component for demanding applications where consistent power delivery is crucial. It's designed to work with solid roller lifters, which are known for their durability and ability to handle higher RPMs and aggressive cam profiles compared to flat tappet designs.

This camshaft features a 259/268 degree duration split at .050 inch lift, with a 112-degree lobe separation angle. This specific profile is optimized for engines that are looking for a significant torque increase. A critical aspect of this camshaft's installation and longevity is its requirement for a Melanized or Nitrided distributor gear. Using a standard cast iron or steel gear without these surface treatments will void the warranty and can lead to premature wear on both the gear and the camshaft's drive journal. It's important to confirm your engine's factory setup; this camshaft is intended for blocks that do not have a factory roller camshaft or the specific oiling groove found in 1955-1957 rear journals.

This COMP Cams camshaft fits a wide range of Chevrolet GEN 1 Small Block engines, including popular displacements like the 350, 400, and 383 strokers. It's a popular choice for builders working on vehicles such as the Chevrolet Camaro, Corvette, and various C-series trucks and Caprice models from the 1980s and early 1990s. Always consult the manufacturer's detailed fitment guide and installation instructions to ensure compatibility with your specific engine build and to verify the correct distributor gear is used.
