Using the 2011 3.36 gears in an 6.0 EX?

So I'm thinking about getting the 3.36 gears from a 2011 superduty and putting them in the 05 Ex. Its 90% of the time on the highway and running 75 to 80 mph. I think it will improve the mpg, but I'd like to hear what Dave and anyone else thinks.

05 6.0 Excursion EB 4x4 auto

95 7.3 F-Superduty XL PSD Auto Mechanics Truck
94 7.3 F-Superduty XL PSD 5 Speed 12ft Flatbed
93 7.3 F-Superduty XL IDI 5 Speed 12ft Dump bed

It should help MPG some.

Discuss this with your favorite automatic transmission guy and see what he says.

It will be a little laggy in town, and hard on your tranny. Kinda like running 38's with 3:73.
