Enginetech bearings and rings

IIRC, there are some markings on the SN pad of the block that have special symbols for any undersized main or rod bearing used in the factory. BTW, do you have a dial caliper? If so that will be accurate enough see if the journals are all standard; any journal being tuned down .010" or .020" will be obvious with a caliper. (Checking actual wear is best done with a micrometer.)

I can't say I ever paid a whole lot of attention to the bearings I take out and toss, besides the STD markings, so can't be of much help there.
