8.75 Strength?

Just out of curiosity, if a 9 inch Ford can handle it, why can't an 8.3/4 Mopar? And why a turbo 400 instead of a 727?

From what I see in the replies here, you might as well run an GM or Ford motor as well, hahaha :)

He mentioned the th400 because of money reasons. The th400 is less costly to build than the tf727. Having never built a 727 I can't say yes or no. You could build the Dana and have it narrowed and be money ahead of Time over the 8 3/4.
