I never understood this?
Seriosuly, you want to make 500hp, and get 20mpg?
I never understood this mentality, let me make it faster, AND get good fuel mileage.
Sounds to me you don't need performance if your worried about how many mpg's you get.
You know how many MPG I get to a tank???? I have no idea, because frankly I don't give a ****..Its performance, so therfore when its empty...re-fill it

OP-As I said before...it all depends on what you want to do with the truck. Putting in a T-56 and still having a functional 4WD is going to be tough, but it is possible, I think. Unless you just really, really wanted or needed a stick I would stay with the 4L80E. You can put a Trans-Go manual valve body in so at least it feels like a stick...better than nothing, I guess.
