The COMP Cams CS 290Xo-6 camshaft is intended for 3/8–1/2 mile tight-track oval racing on 360+ cubic-inch engines with 12:1+ compression and a four-barrel carburetor with good intake and exhaust. It targets high-compression short-track setups needing stronger valve events. Note: 1955–1957 small-block Chevrolets with a rear-journal oiling groove require a specific groove-style cam and are not compatible with this listed part.
