Crank Hole Finish Size For Pilot Bushing

Chrysler made it really hard for swaps by not drilling all the cranks for a pilot bushing.

On the cranks I have that were factory drilled then I of course use the bronze pilot bushing.

On cranks that are not drilled, I usually drill them out. If you drill it out you will never get it precise enough to use the bronze bushing. The idea is just to drill it out enough so the input shaft fits in there without making interference contact within the crank. Then I get a hub bearing. This avoid cutting the input shaft down which in my world is a huge no no and it gets you close enough and you can always use a hub bearing to prevent the input shaft from flopping around.
