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 looked into the coated gears and decided to try out a bronze gear and be very careful to limit the distributor shaft vertical play using a slip-on (screw-type) collar on the shaft. Can't tell you how that's working out, yet, though. The coated gears have warnings against using them w/ high oil pressure, same as the composite gears. I've been cranking 60-65 psi hot and don't want to find out the hard way what their true limit is for handling that sort of load on the gear.

I don't mind being the guinea pig for some of this new stuff. When my car hits the street we will have some empirical data. Thanks for the feedback Brad!

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

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.

I'll hit them up on Monday and see what the deal is with running a HV pump. I can't imagine it would be that much more force to drive a HV pump over the standard volume unit. If I remember right the HV's are designed to pump 25% more volume. Edit: I checked the Melling website and the HV spec is 25%.

I seem to remember that you can use a steel gear, not iron, on a steel billet cam with no problems I had a customer do that years ago on a street steel hydraulic roller cam for a 302 Ford, Comp Cams change the firing order on that cam to the Windsor firing order There where some other problems do to his inexperience on steel camshaft cores, he ate two of the stock distributor gears before buying the correct steel one Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

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

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.

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.

I guess if the coated steel gear doesn't work out I'll shoot for the bronze unit on "take 2".
