Hey all. I'm getting a family vehicle because my daughter is on the way... So figured why not get a suburban!?

anyway it needs a motor and I found a guy to trade a my nv3500 for a lt1 out for 95 lt1 motor. The suburban is a 87 year so t had tbi... What will I be poking at for a swap? It has the computer and wiring harness with the motor and the suburban hasn't been hacked up. Any insight? Thanks!!!
