I just acquired an aiming fixture for the spray-oiler nozzles in the oil pan. (Thanks, Evan!) That's a very important part of doing a quality rebuild of a Babbit rod engine, or one that has been converted to insert bearings, since the rod oiling is the same for either one. The owner of the place where I bought one of my crankshaft grinders, King's Crankshaft in North Carolina, tells me that he would be able to drill a 216 crankshaft for internal oiling of the rod bearings, but the first one he does would involve a pretty considerable programming charge for his CNC equipment. Since he makes most of his living whittling NASCAR crankshafts out of solid billets of steel, I'm sure he would be able to do a good job!
