Identifying 440 Six-Pack Torqueflite

I have an A-727 gearbox that I just pulled from my Jensen SP. It was behind a 440 Six-Pack engine. Both engine and gearbox are original.

I have heard that the 440 Six-Pack engines got the Hemi 727 trannys. What I'd like to know is how to ID the tranny as a Hemi 'box or not without opening it up.

In case anybody's wondering, I pulled the 727 to put in an A-833.
