Thanks for all the advice from everyone. If a 4 blade worked for 35 years, why wouldn't it work now; I keep asking myself that. But I will replace it first. Then the pump. As for the radiator, it was completely gone through during the restoration in 2011, but maybe they didn't really do much to it.

Did those cars not come with a shroud? I'm not well versed on the early A's so I'm not sure. If most of your issues are at idle and low speed a shroud and different fan might indeed help.

Also there was a thread a few weeks ago where someone was chasing overheating issues and it turned out to be the impeller on the water pump shaft was spinning on the shaft and not providing sufficient flow.
