Sherwood, sounds like a plan, let us know what the total start up cost is and the retail cost for a set is

I had that thought after I posted and the answer is I just don't know. I can tell you that in my industry I have seen setups where they try to use bearings as wheels on machines where a winder shaft is removable. Two bearings on the bottom per side that the shaft rests on then a third bearing clamshelled on top, the result is always a badly worn shaft. In one case however this did not happen and they where using a hardened shaft. Based on that and my intuition I'd say equal hardness would work fine. I'd also guess that thee factory cams are harder than a hydraulic type cam since they have to take the hammering abuse of valve lash. I suppose you could machine press on covers for the bearing shells that were equal in hardness to the factory cam. They would have to be precision ground however.
