The COMP Cams .009" oversized composite distributor gear for GM SBC and BBC applications is made from carbon ultra-poly and uses a .500" inner diameter. Built as an oversized option, it provides an alternative for installations needing the .009" increase and is compatible with typical camshaft gears in small and big block Chevrolet engines.
