David,
That's what my BN2 and BJ8 run at highway speed--except in Death Valley
at 115deg--both with stock but re-cored radiators.
It's sitting still at idle that hurts; what does your car run after a
couple minutes sitting at idle? As a side note, the only thing that
really helped for the BJ8 was the 7-bladed flex fan and shroud kit you
and your dad used to sell. But the fan was just too dang loud at
idle--it blew dust out from under the car sitting still--but I still
have the shroud mounted.

<div>We have been dealing with the British Car industry
for only about 70 years, from an independent shop in
the 50s and 60s, then a BL dealer in the 70s and 80s.
Then back to an independent repair shop dealing
strictly British Cars the entire time. </div>
<div>Â </div>
<div>WE have dealt with running hot and overheating the
entire time. Up until about 10 years ago we had been
installing a special high efficency radiator core in
all our radiators. We would not paint the cores,
change the necks to a short neck allowing a higher
pressure cap, correct thermostats, installed air ducts
correctly. All of these things helped. </div>
<div>Â </div>
<div>I am personnally hesitant to make changes until I
have installed in my own personal car and actually
seen a difference. On my BN4 I have a highly upgraded
motor, a 3000 motor that is bored .060 over,
perfomance MSD ignition and much more. I was
continually having hot running problems here in the
central valley of California with the summer temps
always in the high 90s and upto 110. </div>
<div>Â </div>
<div>I removed one of my upgraded radiators and
installed an alluminium radiator, with 2 rows of 1â??
tubes. The original Healey radiator is a 2 row core
with 1/2 tubes, the upgraded core we have been
installing is a 3 row core with 3/8 tubes with a new
style fin. This esentially gave us more tube to fin
area as well as more fin to air surface.</div>
<div>Â </div>
<div>Now with the newer alloy radiator we gained more
tube size, more tube to fin and more fin to air
contact, This making better cooling.</div>
<div>Â </div>
<div>Now for the test, I installed the alloy radiator in
my car, and immediately the running temperature
dropped by about 10 to 20 degrees depending on the
day. However I still had an issue with slow traffic
speeds. It was much better but I wanted to make it
better. So I installed a pusher fan on a thermostat
set at 180 degrees, and now all the heating issues are
gone.</div>
<div>Â </div>
<div>So maybe if you compare equal sized radiators with
equal fins and tubes, the copper brass radiators are
better. But my own personal test in my car proved to
me that the alloy radiator was the cure.</div>
