Andrew,
Just be carefull as the original replacement bearings were supplied in a ' semi finished ' condition . The idea was they were to be ' line bored ' , as per the manual . I think the original part numbers will be for those semi finished shells. Not many engine shops do the line boring work any more , and it's a very time consuming, therefore, expensive process. The 216 precision shells didn't make an appearance til around 1948 ..they were made to fit the earlier motors pre 48 , as well as the post 48 motors.
I've got a booklet here put out by GM , on the precision shells and how to install them with the motor in situ. You still use the shims , per the older type shells, which is interesting .
