The 200 made it back to my brother in law's house, so he can continue working on it. I continue to be amazed at how quiet the engine is. I sometimes have to glance at the oil pressure gauge to make sure it's still running.
 The temp sender in the engine before wasn't working. So we had installed a new one when we rebuilt the valves, as well as a new 160 thermostat. The engine seems to run warm, which I'm assuming is due to the radiator. Probably needs to be boiled out. But the gauge seems to read higher than others.  Back of the water jacket  Top of head  Upper radiator tank  His plan is to remove the radiator and have it boiled out. No leaks right now, so hopefully none get opened up when it's cleaned.

To me, 180°'s is normal operating temp. The 160°F thermostat represents the bottom operating temperature of the engine after warm-up, not the upper temperature.
Also, because these senders all work based on total resistance from the gauge, through the sender and its respective engine ground, they can vary. Then add in any gauge calibration issues, and actual engine temp vs gauge temp can vary. My car has never read dead center on the gauge. On my '54 gauge, it read T E M P. Dead center would be between the E and the M. It generally points at the M, and reads at about 185. An engine that runs too cold is a sludge factory, hence the reason for the thermostat.

Some years ago the subject of possibly improper temp gauge readings also came up. At that time another forum poster did a workup on his 54 which was considered to be working normally. He documented the temp sender resistance values and gauge readings under different temperature conditions. If you decide to dig into the sender and gauge any farther on your car perhaps that discussion and his data might be of some use.

Good to know. My bigger concern is that the engine temp moves up rapidly when at rest (almost to the "hot" line), rather than staying mostly stable. Driving seems to be decent. I'm also not seeing a huge temperature gradient from the top tank of the radiator to the bottom tank once the engine is warmed up. Maybe 10 degrees different at the most, which leads me to believe that the radiator is plugged up.

Slipping fan belt? If it gets hot when stopped but not when moving.

Could be, but I think I remember it feeling normal when deflected. It's not a new belt though. Brother in law will have to check that since the car is back at his place.

I'd check the fan belt for proper tension, and be sure the radiator core isn't full of dust, lint, and small insect debris. That stuff can embed itself deep among the air passages in the radiator core and restrict airflow. I'd wet down the radiator and blow through the core from back to front with an air gun to be sure it is clear. If a fan clutch is present, be sure it is working as it should. Any missing shrouds should be replaced. If the radiator hoses are old, they may have internal issues than can block flow, especially the lower hose. If your heater core is bypassed, that can cause the engine to run hotter. In warm weather, it's best to have the heater control valve shut, and if the heater core is bad, plug the heater coolant supply rather than bypassing one to the other.

Hoses are new and the lower hose was installed with no kinks. Thermostat is new, heater core works as it should, no fan clutch, and no fan shroud. I can almost guarantee the radiator floor is restricted. He's planning on having it boiled out as a radiator shop, hopefully within the next month. Hoping that does the trick.

The specification for that radiator's gravity flow is 39.1 gal/min. Have him see if the radiator shop will test it after it is boiled. I have yet to find a shop that measures gravity flow, they seem to watch the water flowing out and say it looks good. Quote: My bigger concern is that the engine temp moves up rapidly when at rest (almost to the "hot" line), rather than staying mostly stable. Driving seems to be decent. How fast are you driving when it "seems to be decent"? I removed the non clutched fan from a track car to eliminate the power drain and measured the speed required for proper cooling without a fan to be 40mph. The point being that above a certain speed the fan is unnecessary for cooling and you may need to go slower to test the fan aided cooling. I have not tested a Packard to determine the unaided cooling speed.
