The COMP Cams CB XS274 S nitrided camshaft is an Xtreme Energy solid-flat profile offering very strong mid-range torque and sharp throttle response, recommended with a 2500+ stall converter. Nitriding increases surface hardness per the spec. It suits heavy street/strip and bracket applications where midrange punch and throttle response are priorities. Source notes the 2500+ stall requirement and nitrided treatment.
