If it was me i would look in to a ls swap the 5.3 are still cheap enough and easy to get.Use a 4l60e with the motor and get a adapter and run a np205 so you have a good t case in it.The push button 4x4 you want wouldn't work unless you used a ford front axle in the truck.To me thats a lot of work to change axles and have a crappy t case in it.The push button t cases and newer ones are aluminum and chain driven not the strongest thing made.Something like the np205 which is steel and gear driven is a stronger case and less parts to go wrong.
