How do i make my mopar a daily driver??

Get a Chevy for the winter, but if not,then;
1) Clean out the heat crossover passages
2) Make sure the EGR is functioning properly as designed, or not at at all.
3) If your 84 truck had a Holley 2bbl, I recommend to get something else; they require a lot of reworking to be trouble free, over the temperature range you are experiencing.
But if you keep the truck carb;
All the truck systems need to be transferred over to keep it, including;the sparkport,the electrical choke timer mounted on the intake,the heated inlet air system,the charcoal canister, and whatever else it was using, but if a lean-burn, leave that behind..
No matter the carb; install a brand new electric choke element and ensure the choke pull-off is working . If your intake does not have a heated chokewell, I wouldn't use it.
4) Make absolutely sure the Vcan is working. I would throw the truck one away, and get a replacement with as many degrees advance in it that you can find. If your D does not have provision for a Vcan or a working mechanical advance; throw it away.
5) install a 195 stat and flush out the heatercore, make sure your coolant can't freeze up, I hate when that happens. You need more freeze protection than you think; when the cold air gets pulled thru the cold rad by a direct-drive fan, ambient temperature doesn't count anymore.
6) spare parts; ballast resistor, fuel filter, fan belt. And the tools to install same.
7) get a dog to lay on your feet, cuz there is practically zero insulation on the floor,lol. Seal up your firewall openings and make sure the vents also are sealed, and I stuff insulation into mine. It's never gonna get warm in that Mopar; even brand new I had to wear a snowmobile suit in all my As. Not quite so bad in FMJs. Don't even start on my 71 Monaco.
