The COMP Cams CS 296B-R4 camshaft is a late-model small-block Chevy race profile recommended for 388–406 ci applications on short tracks, delivering strong torque and throttle response for close-quarters competition. It follows COMP's compatibility guidance: 1955–57 SBCs with a rear-journal oiling groove are not compatible with the listed part numbers. Use only melanized or nitrided distributor gears; cast or untreated steel gears may void warranties.
