I've got exactly the same issue here in Aus with my 426 63 Sport fury.
It ran hot so I got the 4 core radiator cleaned, then fitted a high flow
thermostat (which made a big difference). I also bolted in a new water
pump
and made sure it was the cast impeller and not a pressed one.
On the highway its beautiful at 170/180 but as soon as i stop (and the
airflow
stops) it starts to run up past 200. Fan is a flex after market unit so
I'll
swap it out with a steel factory item and fit a shroud. After that its a
thermo I guess if I cant get it under control.
Sounds like we all have similar issues..... does anyone know where I can
get a
shroud to suit? or do they have to be custom made? Being in Australia
doesn't
help me I guess.
Snappy.

I have been having heating issues with my 472 in the Polara. It only
has the 22" rad. I tried a 7 blade direct drive flex fan, no good,
have an original 7 blade direct drive max cooling fan, no good, and
then what the car came with a VERY light, plastc Flex-a-lite direct
drive fan. As long as the car is moving the engine runs at 170-175
degrees. When I stop she'll go as high as 210 before I turn the car
off. Since installing water wetter and a 165 thermostat it has not
gone above 205, but I did not have a shroud. I installed a date
correct fan shroud last night and we'll see this weekend how it goes,
I'll keep everyone posted. Next step is a viscous fan if the current
set up doesn't keep it cool, after that, electric fan for sure, I
want to keep it looking as factory as possible. I know, I know, the
472 is not factory, but it keeps brand X enthusiasts guessing.
