allison mt654 in a 87 f350?
 

Thinking of attempting exactly what the title says. I have a healthy mt654 Allison a sae engine adapter starter and flex plate available to me. The trans is a freaking monster compared to my 727 but not much larger than my nv5600. Truck is a offroad toy that I beat the hell out of it already has a divorced t case and I'm sure I would need to do a body lift and some cutting. Just curious if it's a stupid idea or not. Seems a lot cheaper than a 5k fully built 47rh swap
