COMP Cams Camshaft CS XS268S-10

This is the COMP Cams Xtreme Energy CS XS268S-10 solid flat camshaft, designed for Chevrolet Gen 1 Small Block engines. It's a popular choice for street machines looking for an improved idle and more power, especially when paired with a higher stall torque converter. This camshaft is built for performance and is a solid option for many classic Chevy applications.

The XS268S-10 features a 230/236 duration at .050 lift, making it a noticeable step up from stock without being overly radical for street use. While it can work with a stock torque converter, you'll see the best results with a converter rated around 2000 RPM stall speed. This camshaft is intended for engines with flat tappet camshafts; be sure to check your block for a factory roller setup, especially on 1985 and newer models, as this cam will not fit those applications. Early 1955-1957 models also require a specific oiling groove on the rear journal, so confirm your block's configuration before ordering.
