360 to 700r4

With a 700R4 you would need to add a brake pedal switch and wiring, along with a vacuum switch for the overdrive operation and converter lockup operation. It can be done with manual switches, but it's easier to drive when it works correctly.
A 700R4 still won't fit without torsion bar crossmember or floor pan modifications, or maybe both.
Not sure about the adapters; never put one behind a Mopar engine yet.
