904 For Towing Duties?

If i was going to sink money into one I would pull a 727 from an RV that has all the heavy internals and build it to put in there. That being said, ive been towing stuff for years with my V8 4x4 Dakota assuming it had a A518 behind it but one day I jacked it up and it was an A500 which is basically a 904 with overdrive and lock up convertor so I would slap a big trans cooler on there and go towing, build the 727 and set it aside for when it pukes.
