Rod bearing sizes ??

I need some help to figure out what size bearing is this I had purchased this engine block from a sports shop it came into a crate I don't know if it's brand new or it was a core that got rebuilt now I'm just changing the internal so I can put some nitrous in it like to know the bearing size is it stock or is it under size. Anyone can tell me.
Thanks.

yes .25us

Im thinking that means 0.25mm undersized, or 0.010".
