1991 K30 4l80E or NV4500 behind Cummins?

[mud slut 350]

So I have a 91 K30 which had the 6.2L in it. I bought the truck off a guy the truck had broke down on him and it was setting on the side of the road. I got his number from a note he left on the window saying not to tow will be removed shortly so i called him up myself. The trans was blown and only moved in reverse, barely. he said hed sell the truck for 500! No rust needs a fender engine ran great. x military truck d60 front! So i bought it off of him the truck sat for a while i kept it running though pulled the axles for my 82 and then sold the engine. Its setting in my driveway now with stick axles under it for now just to roll around. I want to put a Cummins in it and pretty much do a complete frame off make it a daily driver/Hauler. Im not sure what tranny to put behind it though. I want a stick so i was thinking the 4500 but was wondering if anyone has ever done that combo or not. I was also considering the 4l80E which is already in the truck id just need it rebuilt. or any other suggestions let me know! pics of swaps like this would be awesome too!
