Worked on the car today and here are a couple of pictures of the crane gear I put in three years ago on a used solid roller cam and HV melling pump. No wear except where I had to use needle nose to remove it. Cam looked great too.

Same experience here. I have over 5700 street miles and hundreds of dragstrip passes on mine. I pulled it this Spring to manually prime the pump and it and the hydraulic roller cam gear looked like the day I put them in there.

That is very good info, thanks for posting it. I have a crane gear but I was afraid to put it in because I thought it is too much of an unknown to run on drag week, where it could fail in the middle of nowhere. Now I have the confidence to install it. Thanks again

HV oil pump or standard volume? I put one in my hemi with the HV pump, it has only 5 minutes of run time on it since I built it 8 years ago...

I put that gear and hardened hex-end shaft in my RB when I changed the cam. Got it from Hughes. Remember, they expressly state on the instructions to only use it with a new cam. I guess the operating dynamics are much like a ring and pinion set. Keep them together once run.
Also, use a distributor shaft collar to limit how much the hardened gear can climb the cam gear during operation, which can dramatically effect the contact pattern between the cam gear and driven gear.

Why do the Mopar ones cost 30% more than all the others ?!?!?!? 90% less demand? 50% more material required? "It's a Mopar thing"?

... they expressly state on the instructions to only use it with a new cam. That's direct from Crane, who also states not to use it w/ high-volume or high-pressure oil pumps, IIRC. I am curious how long a cam used w/ a bronze gear might still be OK to convert to one of these treated gears, considering the wear "should" be on the bronze gear up to that point.

Why do the Mopar ones cost 30% more than all the others ?!?!?!? Why would you even consider buying anything from Mopar Performance?! They quit supporting their "heritage performance cars" a long time ago.

They quit supporting their "heritage performance cars" a long time ago. flame Where did you see the words "Mopar Performance" ?!?!? If you go on Summit's or Jeg's sites you will see that the "Mopar" gears cost close to 30% more than the Ford or Chevy. I don't know what MP sells them for.
