probably fan clutch , they go … hard to tell decisively too
have to watch “ new water pump “ as they sell you a 440 pump now. There are variations in 413 pumps i never got to the bottom of myself . But got bit once . Some early block front covers had metal flow directors inside behind pump others did not , add in AC or not , and i believe due to this plate the pumps changed in how far they reach into cavity . . if you put a 440 pump in you can end up with a space behind impeller and it pumps very poorly . I did not measure any of this at the time but someone may know . Confusing and erroneous data out there on this .
discussions with parts guys can get heated all they know is numbers , it is a 440 pump you get unless a part lookup from 1960 but even that crosses in computer to440 pump . Which might work depending on details of front cover cavity
There are articles about adapting i think it was JAG fan clutch too . , as the clutches vary in thickness . tech site has info on that .
Sometimes parts get mixed over 60 years wrong blades etc etc
personally if building new i’d look at modern aluminum 440 covers and pump , at least you kniw they go together , and pump fully evolved
but my bet is fan clutch

Hello again from Delaware,Ohio.
Got a overheating issue.
2 weeks ago drove it 50 miles. Brought it in and it was super hot. Put a new thermostat in and temp guage was in the middle. Flushed engine today 3 times and new antifreeze.
Drove it 50 miles, temp outside 70.
Brought it in and radiator was gurgling and super hot and upper radiator hose was not the usual stuff hose.
Was steaming a little. Had radiator done within 5 years and new water pump also
Infrared temp at radiator cap 200, and engine 240.
Got a week to figure it out or a big no on driving to kokomo.
Thanks in advance.
Ps
Got a new water pump ready to go?
Thanks
