3"in turn down ... so whats the method of addressing the thrust bearing issue?

You can either weld up the thrust area and machine it to the proper size or I believe there are spacer bearings or an Olds bearing that fits.

I've known that for decades along along with not needing a packing tool,
But Op didn't mention anything but cutting the crank,
Was prodding for a deeper answer to see if both oars were in the water

What’s the question? I have a 428 crank turned to 3” mains and will be using the Olds thrust bearing and shims.
