To the earlier question about 727 being mated to the hemi the answer is Yes. To my understanding, 383's and up all were mated to 727 if automatic was used. I believe the 360, then later 5.9 was the largest v-8 coupled to the 904.

This thread also has me wondering what's in my '99 5.9 Durango. Years ago my trans guy told me it was a 727. Visually it looks like one as well but in may be a "variant" of the 727 as described earlier.
