Just FYI, there is no break-in period for new rod bearings, or at least there shouldn't be. There's nothing to break in per se:

Here's BE BEarings break in procedure:

"Recommended Break-In Procedure
Rod bearings don't require any special break-in procedure. The normal break-in procedure of running an engine soft at low RPMs is intended to help the piston rings seal and to wear in other metallic parts that come in contact with each other. Rod bearings don't make contact with the crankshaft because an oil film separates the rod journal from the bearing itself. This is why replacing rod bearings doesn't require any special break-in procedure.
Oil change during break-in is optional. While it's not strictly required to change the oil shortly after changing rod bearings, it's not a bad idea either. When installing new rod bearings, it's expected that assembly lubricants will be used. After a few miles, these lubricants will all dissolve and will be mixed in with the running oil. If you do change the oil after rod bearing installation, we recommend to change it after about 400 miles."
