I made some calculations using bearing thickness, crank journal diameter and oil clearance and it should be around:

#1-4
mm 73.001 - 73.097
in 2.8740 - 2.8778

#5
mm 72.997 - 73.093
in 2.8739 - 2.8777


Again, this is my own calculation as the was no mention of this in the service manual. I have a bare block in my shop I want to double check with but can't because of the quarantine. I'll circle back to this thread when I have the chance.
