Don't use that stock intermediate shaft or a used gear of any type. As mentioned above, Hughes Engines sells the bronze gear and the melonized gear. With a new cam, I would use the melonized gear for longevity.
Make sure you use a distributor collar to limit the up and down movement of the gear. Left uncontrolled, the gear can move up and down too much, which really accelerates wear, especially on the bronze gear. Also check your intermediate shaft bushing for excessive play.
I have wondered if cryogenicly treating the bronze gear would be of any benefit, but have never tested that idea.

OP - Who / where is this builder? I'm also located in Northern Virginia. Thx Also, I have a spare new 440 Source bronze gear on shaft , if you need one. However, I also recommend going w/ the Hughes (Crane) melonized gear, if they're still available.

I remember when Chance (or Chase) still worked at Crane. He told me they never had any problems or failures using a stock gear on Mopar roller cams when used with a regular oil pump. Said it was only when you went up to HP or HV did it cause problems.

I believe Crane used iron gears on many of the roller cams they made-pressed on I think?? This allowed the use of the stock intermediate shaft.

This allowed the use of the stock intermediate shaft. they did it on some chevy cams. not easy to do on mopar big block. there aren't any timing concerns when doing a pressed gear on a small block chevy. if the cam was ran with an iron gear for any length of time i'd yank the cam for full inspection. if the gear on the cam has any damage it will probably wreck a bronze gear.

When I looked many years ago all the crane hydraulic rollers for small block Mopars had iron gears. I can't speak to what they did on big block Mopars.
