If it's not overheating, which it doesn't sound like it is, then I would think there is communication somewhere and combustion pressure is getting into your cooling system.
Maybe a warped head? Maybe a crack in the block? Maybe you can use an air compressor and pressure up one cylinder at time (on compression stroke) and see if you get any air in your cooling system? Just spitballing. Hope it's something simple!

Probably a bad head gasket. Or a cracked block, but let's hope for the best.
They have cheap chemical testers for exhaust gases in the coolant, but with symptoms this obvious, I would just start to dive in. I would first re-torque your head bolts. Note any that are not at the correct torque, and by how much.

Retorquing the head is a good suggestion. I had to retorque my head several times on my 327 after putting a new head gasket on to get it to spec. And it doesn't cost anything to retorque your head! Even if it doesn't cure it, but makes it better, you will at least know you're on the right track.

Per this discussion, I went out and retorqued my head. I used 70 ftlbs. and found a couple of the front nuts turned about 1/4 turn before the wrench clicked, probably 5 of them in total. I also pulled the sparkplugs to see if any had discoloration but they all were the same. I'll order a new head gasket and try that but first, this coming week I'll put it back together and run it to see if it's any better. It hasn't mattered if the motor is hot or cold, it just started pushing out the water right away.

Is there anything that you can think of that happened/changed between when the car was fine and when you first noticed this issue?

Are you certain that your water pump is working as it should? Sometimes a water pump will leak air into the system when the engine is running at higher RPM and this can cause water loss. Also be sure the radiator cap is functioning as it should, and that the thermostat is in place and working as it should. Beyond that, a few loose rust flakes or fragments of rubber from a deteriorated hose can plug radiator tubes very quickly, and that can cause water to be displaced as well as overheating and perhaps air ingestion at the water pump seal. If the engine runs smoothly and the plugs look OK, I would check external items like the water pump, radiator cap, any metal water pipes, etc, before pulling the head.

Not really, I had done a long drive (95 mi.) at the Salado Packard meet and with about 2 mi. to go the motor got hot and started spitting water. Since then I have only done a few very short drives with it but I wanted to get it going for some Winter Parade plans.
