Am I dreaming?

It will be fine, mine has accumulated over 125,000 miles, with lots and lots of 7000 rpm blasts, lots of them.
The problems are rarely powertrain or chassis related.The cooling system is probably Priority One. After that, usually just ignition, fuel, or bulkhead-connector; just keep it simple. Just a simple ignition system and simple fuel system

As to cooling;
Install new hoses, and new belts(carry a spare). Make sure you are running a quality thermostat.Make sure your cooling system is easily capable of handling whatever you are gonna run into.
I'll tell you what I got cuz it works, but you can do whatever you like.
I run an ancient A/C rad off a 1973 smogger-teen, with its shroud; and a Milodon Hi-flo HD waterpump with matching Hi-flo thermostat;and a hi-attack-angle,7-blade all-steel mechanical fan on a Ford Thermostatic clutch; and a low-pressure radcap cuz it's easy on the hoses. Mine is 7psi. I do not recommend that you run a 7# cap in Florida in summer, but I sure wouldn't run a 16 pounder. Water used to be the best coolant. I run it with an additive pkg..And you can find water almost anywhere. Hook up an expansion tank, or at least an overflow tank
The best coolant is ridiculously expensive.
For the fuel;
use a new quality mechanical fuelpump and no electric only system. Then insulate the carb from heat and I prefer fresh air sealed to the airhorn so the carb can run as cool as possible.
For the Ignition;
just a regular Mopar electronic system, or equivalent and carry a spare ballast resistor and ECU. You don't need a fancy Multi-Strike CDI. For a coil,I use an Accell square-top SuperCoil that has well over 100,000 miles on it and was new in 2002, so I highly recommend that one with it's matching resistor.
As to electrical;
The bulkhead you can service now, passing each of the ammeter wires through it in one piece; with ends soldered
If the regulator quits don't panic, you can run the alternator into a dying battery by jumpering the field wire to ground,just keep the rpm down. Keep the duty cycle to such that the voltage stays between about 13 to 14.5,and you, could drive a thousand miles. If the battery voltage rises past 15volts, start turning lights on, if it settles to 13.5 to 14.5, just drive; the lights are your regulator. If it gets over 15 with the light on, unplug the alternator. no big deal.. Start your trip with new brushes in the alternator, and a well-grounded regulator. Alternators rarely fail without warning. Even failing brushes give warning. Carry spare brake-lite bulbs; it ain't worth chancing a ticket.

If running with 4-windows down, make sure your exhaust system is sealed and the tips go out to just past the rear bumber and the rear cowl-seal is in place.For a trip, use 4 same size tires and rims and carry a matching spare and the tools to install it.Run the car for a couple of weeks before the trip to de-bug it.
