The conversion I'm working on to put Massey-Ferguson tractor rod bearings in stovebolt Babbit rods will require drilling a couple of holes in the bearing to match up with the dipper hole and the spit hole in the upper section of the rod, and possibly machining a shallow groove in the middle of the bearing. The advantages will be much lower bearing cost, and the ability to salvage "worn out" .030" undersized crankshafts.
