This is an incredibly interesting, technical article on the 4.2 L, 32V, DOHC, "Hot Vee" Motor going into the CT6 V SPort. It is being built within BGA, specifically inside the Powertrain Build Center.
We learned today, in a separate thread on "Cosworth," that the heads for this motor are being made by the renowned Cosworth Engineering. Also in that article is a note that a complete new manufacturing plant was being built by Cosworth just outside of Detroit, and that a major announcement is coming soon on additional manufacturing of components, perhaps even whole motors, for amajor OEM. Is this facility the location of the ME's 2021+ high performance motors being built. That we will now soon. In the interim, for GM performance motor tech junkies, this article is your brad and butter.
First our earlier thread about Cosworth's new Plant (again with thanks to member Fasttoys who found this article).
