Thanks for the response Kees,
Overkill was exactly what I was looking for. I prefer to have excess coolin=
g capacity rather than just enough. It allows for a bit of lost efficiency =
as the system ages.
I don't have AC on the car, but the thermostat kit I used is set up for it.=
I merely utilized the extra feature as a manual switch leg.
I think I'll keep both fans as they maintain air flow over the whole surfac=
e of the core and only run when the temp rises.
I haven't had any issues with the load on the dynamo, but if I do at some p=
oint I have the options of replacing it with a higher capacity unit or swit=
ching to an alternator. At this point I don't want to fix it if it's not br=
oken.

Very nice job.
However I think that two fans of this size could be a bit of an overkill bu=
t I cannot judge the effect of airco as I am not familiar with that in old =
cars. You could try to completely remove one fan (and block the space at th=
e side of the radiator) and see what happens. It would be a lighter load on=
the dynamo.
