My book says 2.311-2.312 diameter for rod bearings (for a 60-62 235, btw). 2.260 means it's 0.051 undersize now from spinning.

For main bearings it says #1=2.6835-2.6845, #2=2.7145-2.7155, #3=2.7455-2.7465, and #4=2.7765-2.7775. (I'd guess you are numbering them backwards)


Hope this helps.


Some of my crap:
