iron or steel distributor gears?

[dirtynails]

I have a Chevy 350 universal crate motor installed on my '83 Blazer and want to replace my original distributor which is an HEI/ESC and went on the original 305 motor. I am looking at a Summit racing distributor with steel gears and a Mallory 85 with iron gears. Does it make any difference which should I choose? I don't want an improper gear material to eat the cam shaft, right?

If its a hyd flat tappet, you want bronze gear IIRC, steel if for roller cams.

I could be wrong though.

Depends on your cam. If you're using an OEM style cam, iron is preferred. For an aftermarket roller cam bronze is usually required unless they are using an OEM style drive.

Unless, as noted, you have an OE roller cam.
