Yesterday I taught Logan how to perform a compression test. I did the #1 cylinder, he did the other 5. All were between 155-165 PSI. After that he installed the spark plugs (thanks again guys for the advice on getting the correct plugs!). I looked for the engine ID pad on the block, under the #1 plug hole, but couldn't see it. The head, at least, is a '79 or '80, maybe the block too. I'll have to see if there is a casting date somewhere on the block.
At the Holley Moparty we bought a fan shroud for an 18" radiator, doesn't quite fit, about 1/2" too tall to allow all 4 screw holes to line up. We started checking the new radiator hoses we got from Rock Auto, lower will work fine, but I suspect the radiator is not the original. The Dart is a factory A/C car, but missing everything under the hood. Bought the upper hose for an A/C car, but apparently the top radiator outlet should be on the right side, the Dart's is on the left. There are two sets of numbers on the top tank: 38086 & 3692913. Did some research last night, the radiator is for a '74 A body 318 Manual 19". Looking at the pics on Rock Auto they don't seem to curve in the correct direction. Guess I'll try to find a flex hose locally.

We actually got it running today, after dealing with a leaky thermostat housing gasket. Filled it with water (again) and it still leaked, but not as bad. First time was because the thermostat slipped during the install, dropping into the gasket area. Went and got another gasket, which had an adhesive side, so I know it didn't slip this time. When we take it off next time I'll reface it with my belt sander.
As it was a slow leak we started it up, let it warm up, and worked on setting the timing. Its been a while and I forgot to disconnect the vacuum advance. When I did it died as it was hooked to direct vacuum, not ported. Got it running again, got the timing close, and tried to adjust the carb mixture. I didn't get any change at all turning the mixture screw in or out. Once the weather warms up (next year) I'll try the old carb in the trunk to see if it's any better. The water has been drained out.
Might do more work on it if we get some slightly warmer days, but I'm not holding my breath. Will probably search for parts (like the correct radiator for it so we can use the correct hoses) and refinish the air filter assembly.

I think we are about finished working on the Dart for this year, it's about to get cold, and no heat in the garage. We fixed the leaky thermostat housing issue, drained the water, and added anti-freeze. While we had it running we found that there is a vacuum leak under the carburetor even though we installed a new gasket, and it's running pig-rich. Found the old carb in the trunk, missing some pieces, but something Logan can experiment with. Probably in the next day or two we'll pull off the carb and take it to my house where we will go through it, and do a rebuild on it. We also found the 3 speed manual trans is stuck in a forward gear, although the column shift lever appears to be in neutral. Not going to worry about that until the spring. When we were running the engine Logan had to remain in the car pushing in the clutch pedal, best to start exercising those muscles now, before he starts driving it...hehehe.

Sounds like great progress. Thanks for sharing. I'm sure a warm day or three will come up where you can tinker some during the winter...
