99 5.3 into 88 4x4

Hello, i was referred to this site for help.

I have an 88 chevy 4x4 witha 350TBI and a 4 speed tranny. I also have a 5.3 vortec outa a 99 chevy truck, complete from pan to injectors and coils and such, but no computer or wiring. I have been told this is a very time/money consuming project. I was hoping someone could help me out... Does anyone make a kit to do this conversion? IS it even worth doing? Im not worried about my 4x4 workin..i can figure that all out later. i just wanna be able to hop in it and start it up and take off. so please, if anyone could help, it would be much appreciated.
