The COMP Cams CS 284Tl-6 camshaft is a baseline late-model stock cam suited for short 1/4 to 3/8 mile asphalt tracks, working best with a 358 ci engine and a limited intake and carburetor. The listing notes that 1955–1957 small-blocks have an oiling groove in the rear journal and the standard part may not fit those blocks; contact the supplier if you require the grooved-journal version.
