Back in the 50's nobody even considered drilling a stovebolt crankshaft for full-pressure oiling. Splash lube was just the way it was done. 50-something years later, it's still the best way to lubricate the connecting rods on those particular engines. Drilling a crankshaft that was intended to be a solid piece of metal might be possible, but there needs to be some reason to do it other than "just because I can"! I'd much rather concentrate on getting the clearances right so the engine can run just like untold millions of others have done since the 1920's.
