Truth about roller cams.... BEFORE you make the switch......

I got a Billet Hydraulic Roller for my Desoto Hemi. After researching the matching parts, got the Crane steel gear. It is relatively common knowledge that billet cams need a bronze gear, and that it does not last in a street engine. It is only recently that the Crane cams billet compatible steel gear has been around. I think you need a third part to your poll. It is specialized knowledge most people do not need to know.
