    The problem with ball bearing camshafts is that the BB OD is much larger than the std. plain bearing, for which the WR ball-bearing case used a 3/4" (smaller) pinion race than the stock 7/8" WL. I don't know of any way to install BB in a case that already has roller pinion.
    I haven't popped a race out of a case but I am guessing that the steel insert in the case has an i.d. of 1 7/8. With the snap ring in place, it's 3/4" deep. A standard R14 bearing is 3/8 thick and they made a double row baring which is 3/4 thick

    This thread is relevant to my current project as I'm looking to convert WL cases away from rollers w/shims, looking at either balls, spherical or timken. Anybody tried this ? prefer to save as much insert material as possible for added strength so looking at using the smaller WL sprocket shaft, information appreciated, thanks, Tim

    Much less drag. I air'd up a regular BB and it spun for like 5 seconds total (after the air was removed), then I air'd up a ceramic BB and it spun for like 30 seconds and far more rpms. Less friction, more rpms and ponies

    It is, but the actual HP gained is very precious.
