You can see a lot of pics in my gallery.
For '08 the air intake from the filter housing to the throttle body is different.
The exhaust is completely different from the manifolds back. The manifolds appear to be the same as the '05s and up.
I suspect the PCM has a different tune, but can get no confirmation on that.
My '05 seemed to have had a more aggressive shift program.
MPG between the '05 and the '08 are about the same. a solid 11 mpg average per fill up. Highest observed 15.5 on a 27 mile run. Lowest observed 8.5 empty, no trailer, into a steady 40-45 mph headwind in West Texas/SE New Mexico.

The 6.2 is dead in the F150. It is still a go as a replacement to the V10 in the SuperDuty.
While the '08 truck is heavier (new stiffer frame, and more "quiet" steel and insullation), I see no differences in what I am getting for mileage, and what many here are reporting. In town only, I get about 10mpg. On my last highway trip, which included a week of city, I had 13.18 combined. This includes a great deal of climbing in the mountains.
My truck has the 4.10's, and currently has 2000 miles on it.
Overall I am very pleased with the economy of this truck. Driller Tom has to realize that the Ford is MUCH heavier than his Chevy, and probably always will be. However, its capabilities are also higher. Thus, no matter what engine he ends up with, the mileage will probably be lower. You just cannot overcome the laws of physics.

The 08,s are indeed heavier. My 08 v10 crew cab long bed weighed in at 8,080 lbs with job box in the back of the bed. The 06 PSD crew cab long bed dually that I traded in weighed in at 8200lbs with the same job box. Pretty close weights considering the Diesel is heavier and the weight of the dual wheels and fenders.
Are you sure? I weighed my 08 F-350 dually/ 4x4 / crew cab / long bed / V-10, empty, when I first got it and I could of sworn it came in at 6650 lbs...

If you do decide to pull the trigger, you won't be sorry with the performance. It is a quiet, smooth, and powerful engine. I had an 05 F-250 Crewcab 4wd and loved the V10. It is my favorite gas engine hands down. I got around 7 towing a fifth wheel and averaged 13 highway unloaded @ 65mph. I switched to a diesel in 07 as I do alot of towing in the summer and that is when they would jack up the price of gas for the vacation season. Now that the price of diesel has gone nuts I am starting to think about the V10 again.

How is is possible that these engines can differ that much? My mpg is at 1900 rpms approx (68 or so), one person, no load, flat roads.
