I have a couple hydraulic roller FEs running around with the Crane gear in them. So far no issues, but really not that many miles - maybe 5000 cumulative to date. The MSD billet distributors I like use a .531 shaft and a 460 gear.

To tell the truth I have not had severe wear issues with the bronze gears in FEs. I suspect that the Chevy guys have more issues since they lack the cam thrust control of a Ford. Most of my serious roller stuff sees pretty modest miles - but my own personal car ran for years before I replaced the bronze gear, and I only did it then because I changed distributors.

I have also gone to the larger Chevy roll pin when addressing a shearing problem. That way I can usually salvage the gear and shaft while making for a stronger assembly.
