Ive only ever had 1 overheating problem in 20 years when i had my motor
rebuilt to stock 326 2v, and the original rad couldnt cool the new motor ( a
new motor will run much hotter until it breaks in more) I replace the stock
rad with a 3 core rad and never had another issue. Although my car is bone
stock.

Q: Why do most of us have this issue?
I have always been perplexed by that because... I don't and never have in 40
years of driving mine.
I have used original or stock replacement on everything on my 400HO and have
overheated only once, in the early 1970s when I got a stuck thermostat.
I have used the original and now YearOne OEM-style repro radiator.
Stock 15lb cap with only the stock puke hose which stays dry.
Run stock 9 degrees before TDC timing.
Have all original (or Tech bulletin recommended) vacuum connections.
Stock replacement water pump.
50/50 coolant
Stock hoses, heater core, and even have AC.
I have all the 400/AC baffles and fillers but did run without the lower
dam/baffle for many years but now have it for originality.
I don't have guages but the stock sender for the idiot light. (Once I got an
overheat indication and the original sender had failed.)
Have driven 178,000 miles in -30 winter to 100+ degree summer weather, at
high speeds on interstates and stopped for long perids in Chicago-area
traffic jambs, through mountain ranges and to the top of Pike's Peak with no
problem.
I don't get it.
