The ideal ratio of 50:1 is calculated to include the ~1.8ish reduction given by the T.C., correct?
no. the reduction offered by the TC varies by tranny, so people with autos usually say what ratio they have and make sure to mention it's with an auto.

2.80 (AW4 1st gear) x 2.72 (np231) x 4.88 (diffs) = 37:1

I think this is nearly perfect, 5.13s would probably make it perfect on the street and crawling (39:1). This is with 35s of course, and that 50:1 number came from PBB and the average tire size in that thread was probably 38s.

And what width did we decide we were going to make your next pair of axles? Not '76 F-150, I believe?

79 f 150? Or go with the super wide 05 f250.
