The COMP Cams CS 290As‑14 camshaft targets mild bracket and hot street builds for small‑block Chevy, including applications with small or 471 blowers. A factory fitment note warns that 1955–57 SBC blocks with an oiling groove in the rear journal may require special cams; customers with those blocks should contact the supplier for ordering assistance to ensure correct fitment.
