yah a 3.5 ecoboost would be cool. a 5.0 or 6.2 would be better. I think ford is barking up the wrong tree with that 6.2 the old saying there is no replacement for displacement is over. A s/c 5.0 can make up to 624hp at the crank with a ford racing supercharger. drop that in the raptor, aluminum block so it will shed some weight and pick up power across the board and the mileage would be better or just as bad. But what do I know?

No matter what the change is to the raptor it is still probably the sickest truck on the road.
