Reading engine tags

[Bluezone]

I was comparing the engine tags on my Lincoln MKS and Taurus sho. The body tags (not to be confused with a toe tag), shows that these two cars were made within a month of each other.
Does anyone know how to read these and is there a date code or way to read the date code off the engine tag.
I'm trying to figure out if this is the original engine for the SHO.
The top pictures the MKS and the lower pictures the SHO.

He is rarely online anymore so hopefully he gets back to you soon. He works or did work at the engine plant

Well I'll cross my fingers that he can reply. I ran across a few posts on different forums and if I'm reading the tags properly these might be a couple very very early 3.5 l EcoBoost engines. Installed about two and a half weeks apart. If true I don't know whether to be proud or scared. LOL

Those are the dates the engines were assembled, which has not much to do with when they were installed in the vehicles, depending on how the inventory was flowing at the time.

Yes I saw those and figured that they were the installation dates. But manufacturing dates makes more sense. I was also looking at the engine serial numbers. C114400087 and C114400021.
Not sure what happened to FIFO if those are the production serial numbers of the engines. They can't be assembling blocks as produced then.
Engine blocks shoved into a corner and temporarily misplaced?
