The COMP Cams CS 266Xos-8 camshaft is tailored for tight 1/4–3/8 mile tracks and suited to 327–358 cubic-inch small-blocks with roughly 9:1 compression running a two-barrel iron intake and exhaust. It is specified for compact oval racing conditions where short-track power and throttle response matter. Note: 1955–1957 SBCs that require an oiling groove in the rear journal are not compatible with the listed part.
