Two things: the system is not pressurized, and there can be numerous causes, such as a leaky head gasket or a clogged radiator. The number one cause of old Ford heating is a limed water jacket. A 1/16th inch of lime will reduce cooling by 40 percent.

could use more info. original engine ? water pumps ? belt ajusted,? DOES it have thermostats in it, if so remove them and see what happens, you can test them on a stove in boiling water with a temp gauge and a therometer,should open according to the temp marks on the thermostats, 155,180. you can also remove them and see if runs cooler, there are pro and cons on this, I might opened a can of worms here, also is the radiator clean,is it full when hot, [ warmed up to operating temp, ] if you remove the top hoses you might be able to check the impellers of the water pump. see if they are corroded and maybe worn down from rust, V8 FORDS start to run hot when standing at idle for long periods, in 1939 and up FORD DELUXE models had 1 extra gallon of coolant, which helps, lets hear how you made out, please post, hope this helped 37RAGTOPMAN

my guess from experience is that the timing is too far in one direction. I had a 39 coupe, stock motor project car. When I first got it, I started it up and put some tools away. When I came back 10 minutes later, I could smell that it was hot. Played with it off and on until one of my friends moved the distributor around and mystery was solved. Hope this helps.
