The 6.2 engines as used in the Raptor and the Super Duty are the same, there are no internal differences and the two engines are interchangeable. To be technically correct, there are some differences in air intake routing ahead of the manifold and in routing the exhaust, but the basics; block, heads, etc. are the same.
The confusion stems from how the power output of engines are rated when applied to trucks above and below 10,000 pounds GVWR. The F-150 gets a higher rating (at a higher RPM) because it falls into the lighter category, and the SD gets a lower rating (at a lower RPM) because it comes in above the weight line.
I might be wrong, (and please correct me if that's so), but that's what we were told in the Ford Engineer thread a couple years ago.

I took the truck on a 640 mile trip last week I ran from Chicago to Louisville Kentucky to pick up a new atv (well slightly used). The trip was 318 miles each way. I filled up with E85 before we left. It was 2.14 a gallon. I reset the trip and shot down I was in a hurry heading down and I found this very interesting. I ran between 65-80 most of the trip on occasion I ran up to 90 and sat there for 10-15 minutes at a time. We also crawled in constructions for 42 minutes of the trip. When we arrived I filled up again to come home no E85 as it wasn't available. I burned 23.3 gallons going down. That's 13.6 mpg Great. Now the kicker reset the trip drive home same route no traffic and no high speed runs 65-80mph and burned 26.4 gallons on a mix of e85 and 87 12.04 mpg. Oh and on the way down my sliding rear window quit working. My buddy drive it halfway home and he hates big trucks... Him and I went to the dealer Friday and it looks like he's trading his little Ram in tonight.

The Raptor does indeed have a different cam and is also rated with super unleaded (whereas the SD's are rated in good ol' 87).
