All Small Six What size bearings do I have here?

I searched using the numbers on the bearings but can’t find any relevant info showing if they are stock or 10

Maybe measure how thick they are and compare that measurement to a standard one.

With the ford logo, old style, I would say they are the stock bearings. I would think if you deal with your crank, polished or go under size, get new bearings that fit your crank, stock or other wise. I am definitely not the most knowledgeable but that’s what I would do. Info is good

At this point I think they are stock. I have not been able to find those part numbers listed anywhere. These bearings are solid and the replacements I find have an oil groove in the middle

Hi, my guess is that the bearings are original factory size. One way to be sure would be to measure the crank journal. It doesn't matter if the replacement bearings are grooved. You will be fine with either bearing. Good luck
