Engine swap in 1998 Silverado

Hello, I'm wanting to swap engines in my 1998 Silverado. It is a 1500 series with a 5.0 engine. I would like to swap this for a 5.3 engine, and would like to keep my same fuel injection as i used for the 5.0. I was wondering what kind of changes that i would have to do as far as computer/electronics or any other changes? thanks for all your time.
