COMP Cams Camshaft CS 288Btl-6

This is the COMP Cams CS 288Btl-6 camshaft, a solid flat tappet grind designed for Chevrolet Gen 1 Small Block engines. If you're building a performance engine for racing, especially for tracks with fast corners, this camshaft is a well-known option. It's engineered for engines in the 350-377 cubic inch range and works best with open rules, making it a solid choice for competitive builds.

The CS 288Btl-6 features a tight lash design with a camshaft duration of 259 degrees on the intake and 262 degrees on the exhaust. This specific grind is known for its performance characteristics in racing scenarios. It's important to note that this camshaft is intended for engines that use a flat tappet valvetrain. Many GM Small Blocks from the mid-80s onward transitioned to factory roller camshafts, so it's crucial to confirm your engine's configuration before installation. Removing the intake or timing cover is the best way to verify if your block is a factory roller or flat tappet design.

This camshaft fits a wide range of Chevrolet Small Block Gen 1 engines, including popular displacements like the 262, 283, 305, 350, and 400 cubic inch variants. However, it does not fit LT1/LT4 engines or factory roller Small Blocks from 1985 and newer. Additionally, 1955-1957 models require a specific oiling groove on the rear journal, and this particular part number does not include that feature. If you have one of these earlier engines or are unsure about your block's configuration, it's always best to consult the manufacturer's detailed fitment guide or contact us for assistance.
