Are you wanting a steel solid roller cam with a iron oil pump drive on it? If so probably not available, not that I know of, yet for us Mopar BB racers I buy and use the Milidon brand bronze oil pump drives for my solid roller cam motors, they offer three different lengths depending on the oil pump used

There are only 2 or 3 companies making cam cores.
You may try Cam Motion and see if they have the cores. If not, they may be able to tell you if they are even made.
I mean, not to be rude but how many hemi guys need what you are asking for? I've been asking for 7-4 swap cam cores for both SBM and BBM since I can't remember when and when I get tired of the laughing on the other end of the phone I just hang up. I haven't asked for that since about 2014 so they may be available now.

How do you prevent distributor gear wear on a steel billet solid roller camshaft? On my 14-71 blown big block chevy the MSD "brass" distributor gear wore out in about a thousand miles running on a fairly mild howards solid roller cam. Next I tried the "melonized" gear, it also started wearing after about 1k miles, next I tried the "plastic" one that comp cams claimed would work, but it only lasted about 1500 miles before 1/2 of each tooth was worn off and had significant spark scatter. I then installed a Crower billet roller cam with a cast iron gear pressed on and after 10K miles the stock GM distributor gear looked basically like new.

I understand the problem you are having. The issue is getting a core. That's going to be a problem.
Like I said...you can call Cam Motion and see what they have, or if they can tell you has that core, or if one is even made.
There is also Barton, and Tim Banning at FHO who may be able to help.
I totally get what you want. The getting part is going to be an issue.

Take look at the size of the Chevy gear and then look at the Mopar gear size Another outstanding engineering job by Mopar engine designers I ran the same Milidon bronze gear on my old pump gas Duster that had hundreds of runs and over 3000 street miles on it with no ignition timing movement at all IHTHs

I prefer the bronze gear to be the part that wears! When it gets too loose a new one can be dropped in without disturbing the cam.

Never really had a problem w/ mine after 10+ years and a bunch of street time. Replaced it when I freshened it up about 5 years ago. Sure lasts a lot longer than 1k miles.

FWIW I just saw an advertisement is a comic book where Hughes says he has a gear like the OP is wanting.
It may be worth the OP looking into that gear.

It may be worth the OP looking into that gear. Hughes offers the Crane melonized oil pump drive gear mounted on a new shaft, not a camshaft option for a cast iron cam gear.

It seems to me someone with a lathe and the right combination of skill and courage could probably create one, similar to how Crane made the 2-piece small block cores that were used in MP crate engines.
I think it might be a problem to get a person who is inve$ting all that is required in a Hemi to accept the 2 piece design held together with a roll pin, though.
It could be done. I don't think I would want it in that caliber of an engine, though.

I get that, but isn't that gear supposed to be good for any cam gear? Yes, yet at least one person above mentioned that even that type of gear wore excessively in their application. That goes back to my comment that I don't think any gear will hold up if there's something jacked up with the cam gear / oil pump drive gear interface.
