No, not even the earlier ones.
The series 1 and 2 cars "Crossflow radiators" had a "protection
shroud",
but I would hardly call it functional.

4, but 6 blade parts from other Rootes cars pop in now and then.

More power losses too.

Not from the factory.

Here are my thoughts now...
1) Check and verify both static and timing advance.
6 to 10 degrees static timing with 26 degrees of mechanical advance at
4500.
"These distibutors will hace a 13 stamped on the counterwieghts". for 13
cam
degees "26 crank degrees".
Too little or too much advance is not good.
2) Is your car tuned as well as you think it is?
Just because it is running and not popping or belching does not mean
that
the air fuel ratio is even vaguely correct.
Use an EGO or a Colortune kit to verify operation.
LOOK AT YOUR PLUGS!
These little things tell an important story.
If the left two look brown and the right two look white, guess which
side
is running hot "lean"?
3) Is your motor crudded up with scale?
Did you or your mechanic use acid to clean the block during a rebuild?
4) Do you have one of those cheesie platic broken impellors on your
H2O pump?
Are you sure?
5) Did some nasty mechanic weld up half of your cross tubes in your
radiator
to stop a leak?
COMMON CHEAP $(at)! PRACTICE!
6) Does your thermometer work properly/accurately?
7) Does your thermostat work?
Put it is a pot of boiling water, and watch it.
That is about all I can recommend, but I would like to make the
statement
that putting a huge superfast spinning fan is not too prudent to fix
this
problem, as the amount of air that these puppies can draw through the
radiator, becomes rather insignificant in relation to the amount the car
naturally draws at speed.
If your car cant cool itself at speeds above 30 MPH, than you are in
deep
stuff. See items 1 to 7.
If your car stays cool at speed, but not at idle, then consider the
bigger fan.
