5.7 Hemi in Duster

I’m not worried about all the body mods etc. More concerned about wiring harnesses and the ecu. Hoping to do away with the mds. And actually engine parts that need to be changed out. I can get a good deal on this engine. But if it ends up needing a bucnch if things swapped out then I need to reconsider and possible buy something that is already setup.
Just get a Holley Terminator or Dominator and get rid of the factory Hemi CANBUS crap
