The fan clutch is a frequent problem area. Replace and be amazed at
the improvement. Make sure you have a shroud.
I run a 69 350 2bbl w:TH400 auto and a/c. Had a long running problem
with overheating and the clutch did the trick I also tossed in a new
desert cooler radiator since mine was still original and had begun to
build up deposits on the fins which reduce cooling capacity

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.
