With the weight of your 4x4 truck, you will likely see no difference, or worse fuel mileage as the engine will have to work harder.
My dad had an 03 FX4 with the 3.55LS and enjoyed getting 20-21mpg on the highway. So he is stubborn and wants the 3.55LS

What kind of mpg do the newer trucks get with the 3.73?
