2004 LQ4 6.0 mating to a 700r4?

[orange72sub]

Hey guys trying to figure out the best way to go about updating the drivetrain in my 1972 K20 suburban. I am currently in the process of repainting the truck. I would like to address the tired smokey engine next. I want to go with the LQ4 6.0 out of a 2004 2500 truck. The question is what trans should and could I use with this engine? I have a good working 700r4 with an np205 transfercase in the truck now. Will the 700 r4 work? How do I hook up the kick down cable and vacuum advance up? Any thoughts and advice would be much appreciated THanks
