Glad to see you are happy with the car again. Sucks that it cost you years and money to try EFI and it didn't work out.
Funny thing is, I drive my Challenger around and then my Duster, and I like them both for different reasons and can't say which I prefer. But I can say that one thing I hate about my Duster is how it runs when it is cold, and I love how the Challenger runs right all the time. Just hate having to feather the gas to keep it running while rolling up to a stop sign while working three pedals in the Duster.
So I have been slowly working towards swapping a Magnum EFI setup onto the current motor. Just hope it doesn't end the same way yours did.
