putting a ford 5.0 in a 72 Dart

Morning everyone
My question today is how hard and how much engineering goes into swapping a 318 with a 5.0 coyote? I want the modern smooth running fuel injection plus a little more HP without a bunch of huge parts that i'd have to add to the 318. what are the major stumbling blocks that I will run into?
Thanks for any help.

a coyote is wide as hell.. gonna need a bunch of cutting i'd guess.. a LS swap would be much easier in my opinion..
