Although I did not run a shroud on my truck I did make sure all the air coming through the grille was going through the radiator by blocking the top, sides, and bottom. Some things you can to that might help are a shroud, larger fan (more cfm flow), and block areas where air might be going around the radiator instead of through it.

I am having the same issue. Running a 360 MOPAR in a '53 panel.
Stock radiator with a full shroud and 3600 cfm fan. Fan relay is set to kick fan on at 180*. Truck wants to run at 205* to 210* and will spit small amount of coolant when I turn it off. I am going to add a overflow tank this week.
Block and radiator have been flushed. New water pump.
Also going to add back the upper and lower radiator seals.
I still have the 7 lb cap. Could I go to a 14-16 lb cap or is that too much? Would that help cool me down a little? Would like to run a 190 ish.

I tried some "Water Wetter" stuff but didn't see much difference.
I 'll try to find the royal purple.
Think I'll try a 12-13 lb cap and see what it does. Cheap fix if it works. Just don't want to blow the top of that old ford radiator....

Thanks Bob. Thinking I'll have to ditch the original radiator and go to newer cross flow.
Tried the purple ice and a 160* thermostat with no change. Still waiting on the upper and lower seals and over flow tank, but I doubt they'll make the difference.
I am kinda surprised. I've run a lot of SBC's behind flathead Ford radiators over the years with no issues.
I may still pull the Ford radiator and have it rodded and boiled...
