Here is an issue that I have been working through on my 52 with 235.
The motor was originally a powerglide motor, and evidently when they made the motors for the power glides, they did not do the machine work for the pilot bearings in the crank.
That means that the pilot bearing for my crank is 30 thousands smaller outside diameter than the normal pilot bearing.
I did eventually find one and my whole build is waiting on it so I can continue. This only happened with PG motors from 50 - 55 or something like that.
