Does anyone make a composite intermidiate gear?

I know they make a polycarbonate gear for the brand x cars. Do they make anything like that for a big block Chrysler? If my options are still bronze or the new coated gear does anyone have any experience with the coated gear? I treed to get a billet roller cam with a pressed on cast gear but that is not an option for Chrysler stuff.

I made a post about this last week I think....not many replies, but they do make them for mopars, although they say NOT to use them with HV pumps
Are you speaking of the coated gear or the elusive composite?
I think I have two of each style of pump so that is not a huge deal. I will also give Hughes a call and see what they know.

Good question lol...All I know is its a crane gear, and now that I am thinking about it, maybe it is just coated. I will call hughes tomorrow as well and see if they have one of these composite gears for small blocks...might be the ticket for the HV pump and the roller cam- for a street car, having a gear that doesn't wear itself in to the engine oil would be nice

Let me know what they say when you talk to them.
I wasn't able to speak to them (called a couple times and no answer), but from some research I have done, it seems to be the exact same gear as the crane gear but marketed as theirs- as in coated (atleast for SB). Crane says to not use coated gears with used camshafts as it will not wear the teeth in properly and can damage the gear...they also caution against using it with an HV pump, whether the shaft is hardened or not, as the stress from the HV pump will wear it out ( I read of one story on the bullet that scared me away from the composite/coated gear and HV pumps).
I ended up with a Milodon bronze gear and hardened shaft setup from Summit (I had a 10% off coupon that I used). Sorry if I wasn't much help- I would have tried the coated gear if my cam was brand new, but it is used (and appears to be pretty old at that) and I am running an HV pump. Would rather not take any chances.
If you talk to them, let us know what they tell you.

How often are you guys going through the bronze gears.. so far I never have.. the one in my 395 engine has about 900 passes on it and it has minimal wear.. I thought about using it in my 416 in the Rampage(street car) but I found a new one in my stash of junk... it better last a FEW thousand miles

Is melonized(SP?) steel a new word for composite materials?
No. The composite gears are different, "non-metallic" IIRC.
I had a conversation w/ Dwayne Porter on the idea of trying one of the new Crane melonized gears. We came to the conclusion that if I did encounter some wear issues due to oil pressure load on the shaft or whatever, that the resulting particulate that comes from a bronze gear would probably do less damage than what would come off some type of treated steel gear.
End decision was to run a bronze gear, but (as I noted above) be careful during set-up to minimize vertical play of the gear. Can't add anything else now since my junk's still not running again.

I am just thinking out loud here but why not run the brass gear for a little bit to run it in. Then remove it and have it cryogenic treated or some other process that would make it last longer.
Getting old just means you were smarter than some and luckier than others.

My 518 pump gas motor had a new gear put in it when I assembled it in 224 the first time, it had the same gear in it with no noticeable wear when I sold it last year
That is good to know Cab. I guess if the coated steel gear doesn't work out I'll shoot for the bronze unit on "take 2".
