    Thanks. Believe it or not I think the 4.3 gets worse fuel economy than the 5.3.........

    It can be done and it isn't all that hard... relatively speaking... You would be best off to buy a wrecked one that has all of the parts you would need to do the swap. Computer, engine and all of the little parts that you aren't thinking about like motor mounts, fan shroud, and many other small details. It isn't as simple as swapping an engine.

    Welcome to the site!!

    Basically whatever you "think" it's going to cost, double it and you'll be right on the money. Being electronically savy is a huge plus, basically all the extras will make it very expensive. Good luck with your swap!
