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..

Update: been driving the dart for a few months now and it seems very good. I switched the PCV valve to run into the air filter instead of the throttle body wich seemed to pull false air and making it very lean, upped the jet size to 71. and its been alot more easy to start. Electric choke also works fine still some fine tuning to do on the fast idle screw.. but all in all i have no worries on the car to let me down. so to anyone looking to make your mopar a daily driver: Drive it ALOT, then fix/upgrade and tune. thanks for all replies.
