The COMP Cams XS290S-10 camshaft is a pro-street/bracket Xtreme Energy profile that needs a strong supporting build—good intake, headers, proper gearing—and a 3300+ stall converter to deliver intended power. Be aware that 1955–57 small-block Chevys use a rear-journal oiling groove; if your engine is from those years, request the matching oiling-groove cam.
