The motor/transmission will bolt in just fine assuming you have a 700r4 already, but you will need to change the fuel pump to accommodate the tbi. I would try to find a donor vehicle to get everything you need.
I just saw a '88 GMC on Craigslist that someone parting out so I sent him an email to inquiry about the motor.

I forgot to ask about the gas tank from donor as well too since it should have a return line inlet and a pump in it. Will it bolt on too or modification is needed to the frame?

I am still researching on the tranny, I believe that I have a 700 but doesn't ECM need a specific tranny to monitor it or I can use my with the TBI motor if it a 700r4 from a carb motor?

Thank you
