When i drove my Durango R/T 5.9 , i dreamed of having this engine and tranny in one of my cars, but thats were im lost .. not familliar to these swaps , and no one around me as infos too .
Go read some of the builds over at Dakotart.com
There is tons of info on what mods people have done and the performance gains they get from it.
Like forced induction, stroking the motor out, or simply doin a cam swap
All that is needed is a reflash of the stock ecu of what ever you pirate the ecu set up out of.
I personally would love love to do a magnum 360 roller swap into my Swinger. Using a stock ECU set up out of a Dakota or something and adapting it to make it work with my set up.
