Ford with a Mopar engine in it

Now this isn't an A body but I've got an old ford i'm starting to restore. What i've got to work with right now is a 79 f250 ranger lariat camper special. dana 60s front and rear, 4 speed 460 205 transfer case and all that. I plan to put an auto in it as well as a new engine with more power this one is hopped up but has 200k on it. I've always been a ford truck mopar car guy but want to mix the 2. seeming how the big block mopar has high advantages vs a 460 in terms of engine design and also cost. Truck will be winchester grey. Wanting to know what you all think of a 440 727 setup in this truck? It's not like I would have to butcher it to fit and it could all go back to ford as long as a guy has the proper running gear.
