Curious - 2024 GM 2.7 'Turbomax' country of origin - Mexico?

[Probity]

Just a general interest question I have that I've not been able to answer yet....

 

I'm a new (2 weeks ago) owner of a 2024 Silverado WT CCSB with the 2.7. I know Silverados are assembled either in Roanoak (Ft. Wayne) IN or Silao Mexico (mine happens to be a Silao truck, 11/23 made date from door jamb sticker).

 

Researched the 2.7 a bit late last year and in Jan. of this year. All articles I saw mentioned the 2.7 as being from the Spring Hill TN GM plant. When I was researching '23s to buy, all window stickers I saw (regardless of US or Mexico assembly plant) had USA country of origin for both the engine and 8 speed tranny. Have looked at a few '22 and earlier window stickers too, they'll all USA for both engine and tranny country of origin.

 

When looking at 2024 Silverados to purchase, every one with the 2.7 (both Roanoak and Silao assembled) had/has window stickers with Mexico country of origin for the engine (tranny still USA).

 

Which GM plant in Mexico "makes" the 2.7? Does Spring Hill still make 2.7? Just curious......
