Other than the exterior cosmetics and the underhood issues, might be a pretty nice car. At that age and miles, might need a "valve job" and valve guide attention anyway. That'll get the heads off. Find a used intake and put an Edelbrock 4bbl of your choice on it, plus an appropriate air cleaner. Should be a donor parts car for the other underhood items, somewhere. Some of the fire-damaged items might have needed replacement anyway. Plus some 15x6.5 Rallye wheels from a '76 Charger SE. All salvage yard items. Other than that, just some labor. Ending up with a nice car for little money, that could last for a good while as a daily-use vehicle. Later on, a better inexpensive paint job. Not having to hire the work done can be a plus and save costs! Might even make a little money on it, having used it for a few years, in the end? I never was a fan of the '73 front end, compared to the '70-'71, just my personal pref.
