It will drop in and no modification other than a tune. But you will have a massive loss if power!!!

I think you'd be much better off fixing yours versus a negative effect swap. IMO a negative swap.
Like stated though just get all the engine parts from the wrecked vehicle and drop them in.

Right i will loss some power will it still work with out a tune ?
You are right on fixing but due to budget and i got a deal on the 5.3 i will be saving a lot of money of fixing or rebuilt the 5.3 i only paid i
$500 from a friend with 78k miles and so clean and sound perfect no noises or leaks

With out a tune the timing will be advanced too much and it will be dumping in more fuel than it needs. And that's just two of the tunning that come to mind first. Save and buy another 6.0. Less trouble in the long run for you
