I have Googled just about every combination I can think of and can't seem to find out where TH400s are made. I'm pretty sure the TH350s are made in Cleveland and Toledo.

Also, the TH400 has metal tag affixed to it for identification and this tag information doesn't include the TH400 plant identifier, but does the TH350 have a tag of some sort or is its plant and/or date code stamped in the case?

Dale, maybe Willow Run (Ypsilanti) Michigan.

That's a definate start, thank you! None of Colvin's "...by the numbers..." books and the "Catalog of Chevelle, Malibu & El Camino ID Numbers" (a very poor resource I'm beginning to find out) book mention the TH400 plant that I can find.

Hopefully someone with more info than I can chime in with other plants if they were used. :thumbsup:
