8hp90 trans mount

[19 69 GTX]

Ordered a Holley swap kit for hellcat swap into my 69 but come to realize the kit is for a 8hp70 or Nag 1..can we not use the 8hp90

My understanding is that the difference isn’t a physical difference but a rating difference. The 8HP70 is rated for 700 and the 8HP9 is rated for 900 Newton meters of torque.

Any update on this? I have been trying to figure this out as well. I can’t find anything definitive on the interweb.

There are differences car vs truck with the cooler box on the side, otherwise the same from my research.
