The COMP Cams XS274S-10 Xtreme Energy camshaft focuses on strong mid-range torque and improved throttle response for street-oriented builds, recommending around a 2200+ stall converter. Note: 1955–57 small-block Chevys have a rear-journal oiling groove and require a camshaft made for that journal; contact us if your application needs the oiling-groove version.
