KB167 vs KB399

OK. I have attached a picture of the remanufacturing tag and, yes, it was done as per approved Chrysler methods. The shop is no longer in business but my machinist recognized the tag and said that their work was good. I looked at the block as you suggested and there is no match between the numbers on the side of the block and the tag.

What do the two numbers in the "Model Number" area mean?

All blocks have the casting date on the passenger's side of teh block, below the deck, above the core plug holes. The reman should have a part number stamped on the tag too... If it's a mopar reman. That number would tell you what year spec the engine was rebuilt to. Because it's been rebuilt, knowing the casting date does not gaurantee the assembly was built for that period.
