91 k1500 engine swap

I am interested in swapping out the tired old 5.7l and swap in a 454 from an 88 c3500. I am wondering about the computer/electronics. Since they are both tbi motors, i am wondering if swapping the computer with the big block will work. Any help is greatly appreiciated.

Work in terms of what? I really doubt you could run the 454 on teh 350 computer, so you have to swap computers? Are you asking if the wiring will match up?
