91' vs. 87'

[N.E. TMRPR]

What will I have to do to replace a 87' motor with a 91' motor. I have a chance to get the 91' and I understand this is a good year but it has the serpentine belt system and I want to put the AC on it. The motor is complete with alternator but no AC compressor. Are the brackets and compressor pulley available to put on my v-belt compressor? I also need the fan. Is there any type other than the 91' original that belongs on it? Will the 700R go onto the motor with just putting the cable brackets and cable onto the Injector pump? Sorry for all the questions. This is my first 6.2 blazer restoration and engine swap.
Thanks, Ted

the easest way would be to change the parts from 82 eng to 91 eng including water pump as they turn oppsite directions or find compressor & brackets & fan for the 91 every thing else should be bolt in
