I believe I have the capacity to cool it, the top of the radiator was full of scale when I got home, it ran for 15 miles at less than 190, after it crept up I went back to the highway and got up to 55 again to see if it would cool down with more airflow, it stayed where it was. I got that cleaned up again and have socks in to catch it for the time being, I’ll try the vinegar in the block and see how that goes.

It sounds like you may have inadequate radiator capacity. When the air is being forced through the radiator by driving at a steady speed, it can cool the coolant, but when you get in traffic it will not coll the coolant. Your rust scale problem makes it hard to say if it is a capacity problem, so you should resolve that first. Other people have used vinegar, CLR, Evaporust and other types of rust removal products to clean their block with success. Vinegar is the least expensive. Fill the block with vinegar, start and run the engine to warm up the vinegar and then let it set for a couple of days. Remove the water pumps and flush the heads and block. The vinegar should soften and loosen the rust scale and the large opening of the water inlet should allow most of it to drain out. You can also remove the water pumps and use a frayed cable in a drill to loosen some of the scale at the bottom of the block. Then flush it and do it over until the flushed water is clear of debris.

The pictures may not show it but I did the block and radiator separately, I did the two sides of the block, in the upper hose, out the water pump inlet, so reverse flow, radiator is not connected. I do the radiator from the bottom hose up and out the two upper hoses, the other lower hose plugged, never the radiator and block at the same time.

Seems to me that it should be flushed just the opposite of the way you did it...That is, flush through the radiator first and then out the block. This, to keep the "crud" from the block out of the radiator.

I pulled the socks out, another 1/4 cup in those, one side had opened up again, a solid layer of goo and chunks on top of the core tubes in the upper tank, air/water flushed that again and got it clean again. I made socks without seams this time, kind of crude but I’ll try it again, seems like and endless supply of crud in there, has to be a couple of cups so far.

I did some back flushing with water+air, backwards through the block and up through the radiator. I got a lot of cr*p out of the block, the radiator had a little in it, one of the socks opened up at a seam and let some back in. After 3 flushes per side I buttoned it all up, straight water, no thermostats. I drove around town a bit then did 15 miles at 55-60 mph. It hung out around 190 and as I came into town and slowed down it crept up to right around 220 and hung there, I went home and it was bubbling a little in to the overflow bottle. After it cools I’ll check my socks, I made new ones twice as long and closed up the ends better. Does this seem normal or do i still have gremlins? I attached a couple pictures of my flushing rig for both the block and the radiator

I got rigged up to do a back flush through the upper radiator hose with water and the ability to blast some air with it, I'll drive it and get it a little warmed up and then pull the bottom hose and do one side at a time. Hopefully the air will help churn up some more of that stuff and get it out.

I pulled the screens I put in the upper hose ports, at least 1/4 cup of rust chunks, one of them was full, I made bigger ones, I’m sure glad it’s not going in the radiator. This thing runs great, no smoke, I don’t want to tear it apart yet but I suspect that’s in the future. I’ll keep running short trips and emptying the socks for now.

"If you want to get a correct brass radiator for the car at "reasonable" cost, advertising for one in the Parts Wanted section of our club's website might provide the best results. Once you obtain this radiator, you can have it cleaned and repaired as required for less than the cost of a new unit from the vendors previously listed." I agree, the radiator man made it very clear that he could help me a lot more with that scenario. Also keeps more original parts on the road. I'll run what I have for the time being, lots of other things to pick away at before I get there but I'll keep my eyes open. On another note I managed to make some headway adjusting the brakes, I did the fronts, turned out good, pretty much eliminated the pulling to the right. I need to do the backs as well. I need to get it up on stands and grease it, check fluids, etc. I'll do them then.
