The COMP Cams .491" I.D. bronze distributor gear is built for reverse-rotation Chevrolet V8 applications (265–400 and 396–454). Machined from AMPCO-45 aluminum bronze with nickel, its high-strength tooth profile resists wear even under high-pressure oil pump conditions and suits steel roller cam installations that require reverse-rotation distributor compatibility.
