Awesome, keep it up!
Here is my recommendation
1 - When it is cold, put a piece of tape at the cold coolant level. Then next time you drive it and let it cool down again, you can see if it stays stable. If it is, put a mark with a Sharpie and now you have something the check every time when cold. 214 is not a problem AT ALL
2 - If the rattle won't fall apart, it's fine to drive it, but if it will, maybe it's time to fix the radiator mount so that you have power steering and no more rattles. That way you can drive it normally, because my hunch is that it IS a normal driver now.
3 - Said this before, but I'll keep saying to to keep that beauty safe. At some point, do a "nut and bolt" Start from the rear of the car and check everything. Rear axle bolts, driveshaft, crossmember, bellhousing, and keep going forward looking for wires that can burn, loose bolts, you name it. A good day, or even weekend without starting the car could get you to the point that you are FINISHED and the car will be done.
I'd say you are really close, once you get the PS working, I bet the rest is uneventful.
Then we can see who is quicker
Although I assume when you say you are moving north, you don't mean Nebraska LOL
