COMP Cams Camshaft CS 283Tk-R6

If you're building a 355-377 cubic inch late model Chevrolet Small Block for oval track racing, specifically for 1/4 to 1/2 mile tacky conditions, this COMP Cams CS 283Tk-R6 solid roller camshaft is a strong option. It's designed to work with 4-barrel carburetors and large cylinder heads, giving your engine the aggressive profile needed for competitive racing.

This camshaft features a 255/259 degree duration at .050 inch lift, a common specification for this type of racing application. It's a solid roller design, which means it uses roller lifters for reduced friction and increased performance potential compared to flat tappet cams. COMP Cams specifies that this camshaft is optimized for use with a melanized or nitrided distributor gear. Using cast iron or steel gears without these surface treatments can cause premature wear and will void the warranty, so be sure to select the correct distributor gear to match.

This camshaft fits a wide range of Chevrolet Gen 1 Small Block engines, including popular displacements like the 283, 305, 327, and 350. However, it's important to verify your specific engine's configuration. It does not fit LT1/LT4 engines or factory roller blocks from 1985 and newer. Also, 1955-1957 models require a specific oiling groove on the rear journal, and this particular part number does not include it. If you're unsure about your engine's factory setup, it's best to remove the intake or timing cover to confirm whether it's a factory roller or flat tappet block.
