The COMP Cams High Energy die-cast aluminum roller rocker for Chevrolet 265–400 V8s is a cost-effective upgrade for street and moderate race use. The larger-than-stock die-cast aluminum body, needle-bearing fulcrum and roller tip cut friction and lower oil temperatures while increasing valve lift. Specified for 3/8" studs at a 1.5 ratio; snap rings hold the trunnion and bearings in place and support high spring pressures.
