When I brought my 1972 Eldorado out of storage last week, it almost instantly started overheating. I saw no signs of a coolant leak prior to this and have since filled the car with over 2 gallons of coolant and no leak has surfaced. The car drives fine with no issues and isn't overheating; no smoke, no coolant in the oil; etc.
I can't, for the life of me, figure out how this happened.
Has anyone experienced anything similar?
The engine is, naturally, a 500 Cu. In. with 88k on it.

It overheated when you took it out? But now it doesn't? Just coolant loss? Do a head gasket check. You can have a internal leak and it hasn't shown it self. Make sure all hoses are tight to block and radiator.

That is correct. It only overheated because there was NO coolant left. After I filled up the system, there were no problems. No blowback, no smoking, nothing that seemed out of place.
I put a new radiator in last fall, before it sat for winter, and flushed the coolant system then. I keep looking for a sign of a leak, but it confounds me. Since the car had no coolant in the oil or valve covers and it only disappeared while the car wasn't used for several months.

If it doesn't do it while your driving some thing is lose. Puddles? Re check everything, if you had no coolant it' s leaking from a lose fitting or internal.
