I think you should 4BT swap it. I hear that is all the rage.
Or you could throw a hi-tech 12v cummins in it.
If you have to have a v8, do as another poster said, trade the raptor for a loaded platinum or whatever, take the extra cash, write a check to SVC or rogue or someone, wait 6 months, then get your long travel, supercharged V8 f150 back.
If you think resale sucks on raptors, wait till you want to dump your new toy.
You'll end up well over 100K in to do it right, and you might get 50K for it in a year when you want to sell it because "it sucks".
My 2nd gt350 sat at the dealer for 3 damn months waiting for a transmission tail housing. Consider yourself lucky.
