I've heard of a couple of US firms making kits to adapt AOD's to Lima engines-here's a link to one of them-
Ford 429/460 At least in USA models, Ford never put an AOD behind any engine that did not have a "small block" bellhousing bolt pattern. 460 trucks got either C6's or E4OD's.
Baumann makes a standalone controller that will help mate an E4OD to your car.

I like AOD's but for your torquey big block engine in a fairly heavy car, I'm pretty sure the E4OD is a much better choice.
