block number help

what exactly should the block number "match" if its the original engine on a car? I've never decoded one of these things because my car was owned by my dad since new and I never had to worry. But this is for a C2 and I have no idea how to match that number to something.

I hope this helps some. I'm sure there are others more learned than I here that will chime in and fill in other info or correct me if I missed something.
