Yeah, but do GM and Ford use these gears with factory billet steel roller cams or cast-iron roller cams (or are the gears on their cams billet or cast iron)? Most aftermarket roller cams are billet, so there may be a compatability problem. I'd call your cam manufacturer to see if the distributor gear is compatable.

To my knowledge, all roller cams are steel. If the cams were cast iron, there wouldn't be a problem using a standard distributor gear. The gears on the cams are steel. GM went through the motions of installing cast iron gears on the cams but settled on leaving the cam gears steel and using the melonized distributor gear.
