Ford puts a shorter 3.55 rear drive axle on with the 2.7 vs 3.31 rear drive with the 3.5...that is more likely to be the difference in the "little snappier" feeling.

Very possibly, especially considering Ford is sticking with the 6 speed auto. Now if they did something like RAM did and go to the 8 speed, the differences in axle ratio that small would hardly be noticeable until you hit the final gear........in real world driving. According to RAM, a 3.21 8 speed vs. a 3.55 8 speed nets 2000lbs more towing, while it should net more I for one just do no buy its that big of a difference when all things are considered, especially since hardly any of the manufacturers are held to some kind of standard. I have driven both ratios in the RAM, you don't notice any difference until 7 and 8 gear. That's it. Now with Fords 6 speed, you might but that is still a very small ratio difference that you mentioned.
