The COMP Cams CS XR276HR-1 cam and lifter kit includes camshaft, lifters, assembly lube, decals and instructions for a complete upgrade. For modified TPI systems this grind needs injector, plenum and runner changes along with exhaust work and a 2000+ stall converter; custom tuning is recommended to calibrate fueling and timing for the altered torque curve and idle.
