How to read engine serial number?

74JU2U1023071 is my serial number on my 1999. Is that early 99 or late 99? I don’t know. I can’t figure it out at all. Please help.

Is your engine original to the truck? If so what's the manufacture date on the sticker on the driver's side door jamb?

It has a custom paint job. All the stickers on the door jams are gone.

Do you have a sticker like this on the driver side valve cover?

It does not. It is gone. Anything else I can do? Or can it be deciphered from the engine serial number?

That might be the International # .....so if you find the corresponding Ford https://www.thedieselstop.com/faq/94...nterchange.pdf
along with the Ford VIN you should be able to find the Build date...at least I think
This is the International numbers deal https://www.thedieselstop.com/faq/94...veic_final.pdf
Good Luck

I haven’t checked the plenum diameter, but the turbo housing does have 5 bolts.
