That would be labor cost. Used engine is $8k to $10k and you should change the rod bearings.

Main bearings can fail but do not seem to wear as fast as the rod bearings. There have been many cases of failed rid bearings buy only a few cases of failed main bearings. It is much more labor to change the main bearings but if the engine was out of the car I would consider it assuming it can be done from underneath due to the 2 piece engine block.
