I prefer Ford as well unfortunately thier engines have been garbage sense 2003, both gas and diesel. So I have a Dodge,,, and yep its a hunkojunk, but it easy to work on, and the Cummings is a great engine.
Supposedly F450's are avaiable with Cats and or Cummings, no Idea if its true or not, but Id never own a 6.0 or 6.4 power joke.
I mean get a clue Ford, your engines are so bad you have created an aftermarket called Destroked. Shops are pulling powerjokes out and replacing them with Cummins and Cats.
