short shaft 727 good for anything?

The short tail shaft trannys came in heavy duty applications and all have a bolt on flange, some with a parking brake arrangement, others just the u joint flange.

They are good for heavy duty trucks, 4 wheel drive divorced transfer case set ups, possibly a dragster, but why, and rear engine wheel stander applications. I'm sure there are other applications, the possibilities boggle the mind. :)
