Technical Data for M103 engine needed
 

I am trying to decide whether to buy standard or undersized main and connecting rod bearings. I have the clearances measured off of my crank but I do not know the specifications of the bearings. Can anyone help me out with this information?

Unless you plan on turning the crank, use standard bearings. Have you mic'ed and found the journals in spec?

I have the dimensions at home if you need to know the original journal size.

Good luck,

The main bearing journals were about 2.3065" and the rod bearings were about 1.8875". Should I still go with the standard bearings? The engine had a 104,000 miles on it.
