How do i make my mopar a daily driver??

Hello mopar guys!
I have a 360 in my 69 dart it was in an 84 D150 before. What do you think is the most important parts for making it a daily driver/make it more reliable? I was thinking about an EFI system, but which one? is there options to make a carburator just as reliable? I live in norway so i have very rough weather from time to time, from 14 F to 70 F temp weather in the summer..
