I got my 440 rebuilt and the builder used a Comp Cams 23-600-9 billet steel roller cam. He reused my original distributor gear.

Somone said if I don't use a bronze distributor gear then it will damage the billet cam's steel drive and cause all sorts of problems. Is this true or can I leave it alone?.

If not do I need distributor gear made out of bronze, or one that has been melonized?
