To whom it may be worth something, I toured the HD engine plant in 2016 and got genuine engine build card used in production. I just found it and thought, just maybe a member here that has a 2016 engine might find it to be their engine build sheet. I toured the plant around Mid March. So more than likely the build would be prior to March. See Picture

 

Sorry it’s upside down.

 

Fixed it for you, very cool.

 

At 1690cc, that’s a 103 engine, I do know they were building the new Milwaukee 8 (back in 2016), but it does show MY 2016. Maybe someone can decipher the card.
