About the only thing you can look for is an AOD or some
flavor. You need to find one from behind a 351W for two
reasons. It will aloready be up to handling the 351 with
respect to clutch packs and the flywheel balance is not the
same as a 5.0L. The problem with a regular AOD is the
requirement for the throttle cable to keep the line pressure
correct and operate passing gear. There my be someone arond
who has a likkage kit but, the trans is finnicky and will
destroy itself if you can't keep the pressures up properly.
The AOD-E is the electronic version used from about '92 up
thru about 1995 in cars. They are plentiful. You will need
the small block Winsor bell housing pattern. I don't know
if this was used in the cars.
If you can find and afford it, your best selection would be
a 4R70W which is electronically controlled. It can be found
in the light trucks from about '93 up and cars from about
1996. Folks like Baumann Brothers should have a kit to
operate it making installation about as easy as using an AOD
with a bunch stronger gearbox and a wide ratio gear set to
get the Torino off the line a bit quicker than the AOD.
I think if you go to the Mustang group, you may find quite a
bit of help getting it OD'd
