807 11 ~ Electric coolant pump?

Further information that may be helpful:

Long run today about 20Km @ town road speeds & 20Km freeway, sitting between 100/110Km/hr.
Dash gauge runs @ radiator top tank outlet & max temp reached 65°C after the 20Km dash.
The Davies Craig temp [cylinder head through pump to radiator bottom tank] ran up to 92°C on the freeway after about 12Km, also & with alarm set, started sounding @ 90°C.
Switched off, backed off speed & came down to 90°C very quickly.
Over the whole run the average was about 58°C & 90°C so all in all the radiator, fan etc. kept the in & out temperature differential @ around 30°C.

Really pleased with this fairly simple solution, to my problem & thanks to those interested, plus offered advice.

Thanks Ringer, very good info and results from the real world test!

More to come.
Pump weeped slightly after cool down. Davies Craig really good to deal with. Waiting for bits to arrive & will post additional fit up info & test regime.
Anyone wants 2 original water pumps to suit this engine one near new, other functioning fine, all pulleys incl cam, v belts etc. just pay postage. JG.

Will post pics tomorrow when I've been able to reduce.

Can report that after getting a new radiator made about twice capacity, plus fitting a new Chinese Weber carb, timing with vacuum gauge this car is running like a rocket. Tonnes of torque & acceleration up & down hills. Better than ever!
Noticed after vacuum gauge timed (advanced over timing marks) the exhaust is way less noisy?

Must up the fan switch to about 90*C can't get over 80*C @ the moment.
Electric waterpump & right sized radiator combo should have been done instead of trying to save money. JG.
