I finally talked to a Comp Cams techline guy who seemed to know what he was talking about. He stated: NEVER run a melanized steel gear with a steel billet cam--one should ONLY use either a sacrificial bronze or polymer, which won't last very long. In the case of bronze, about 3 to 4K miles, and with the polymer, about 10 to 15K miles. With the "austempered ductile iron" cams, one can run a melanized steel gear, such as the one Ford Racing makes. So, having purchased a custom ground billet steel cam from Comp, I am stuck with running the bronze or polymer. I am not happy about it. The only thing that makes me wonder about possibly using a steel distributor gear with a billet steel cam, is that Crane offered(before they went down)a steel dist.gear to go with their steel billet cams. Now, I thought all billet steel used to make these cams was #1050, so why not use a steel gear on a Comp billet? But the tech guy was adamant about NOT doing so. Are there forum members who have used a steel disty gear on a billet steel cam with no incident
Thanks, I am stumped.
