There is a guy in Washington who has a Cruiser with a 5.9, 727 tranny, NP205, 60 front and 70 rear. He has it up on 42" tsl's. It's only the 180 HP 5.9, but the off idle torque is incredible. Almost too much.
He also put a 305 HP 5.9, NV5600, NP205, and 60/70 axles, and put it in a 84' Toyota. He had to re-construct the front end support, and the radiator and intercooler share the bed with the two 5" stacks. I haven't ridden in that one, but I am sure it is really fun.
