And the 6BT is mechanical and not electronic. You can put that engine in anything and as long as you provide fuel and electricity to the starter you can make it run. A late model Challenger with a old engine needs it all to run. In the late model cars with the Can Bus system, all modules input to the computer including modules such as power seat, window, HVAC etc. It all has to work or none of it works properly. The only hope in installing a old school engine in a new car would be if someone could design a computer to fool all those inputs into thinking that a late model engine was under the hood.
