Hardened shafts but not bronze gear. I think the op is running a roller
Is it a reground solid roller? I though only the billet rollers needed a bronze gear as even the roller magnums (and every other roller V8) run an iron gear.
Bronze is made to sheer..... and those little specks of bronze stuck my relief spring in the pump, and damaged one of the clover walls in the pump. I don't want/like bronze gear in a daily. Just my opinion, experience.That is freaking ridiculous. I don't understand these prices these days. I know @318willrun had some issues with a brass shaft leaving specs of brass all inside his motor and stopping up the oil pump.
What cam blank did they use? Iron or steel? If its iron, you don't need the bronze. If its steel it was probably uber expensive to begin with and would have still been expensive as a regrind as the steel LA cores are all aftermarket.
At least with an iron gear, you can use magnets to help remove iron grinding from oil. Not so with bronze. I think part of the issue with roller cams is longitudinal cam thrust. With flat tappets the cam lobes' tapers compensate for each other and reduce the "natural" thrust generated from a spinning shaft and the valve train pressures. Rollers have "flat" lobes, and probably need thrust plates on the front of the cam. Not a big deal for factory roller engines, but for engines not designed for rollers, there other remedies are usually needed.Bronze is made to sheer..... and those little specks of bronze stuck my relief spring in the pump, and damaged one of the clover walls in the pump.

Call you cam company and get what they require. If you have issues it had what the recommend.Why are oil pump drives so expensive ?
Seem crazy... almost as much as a custom roller cam !

Not what??Not on Mopars from what I know .
Not what??
Well you are 100% wrong about reverse rotation mopar marine engines. I know SB's have thrust plates. I believe all SBC & BBC needed cam buttons. Not sure about BB mopes and slants.The need for thrust bearing etc.. Chevys require them but we have thrust plates.
Correct me if I am wrong.
