Mike,
Despite being in the Monaro region, we do experience temperatures that can challenge the older cars at times (today's temp 41C - tomorrow hotter). I generally find that our 410 temp ranges around 80 - 85. Driving around town sees this go up to 90 but switching on the fans keeps it at around 85-90 in summer.
The radiator and engine block have had extensive flushing and for a while the cooling system had a sock because the car was inactive for so long.
In this weather, I must admit that I retreat to our modern and air conditioning although I am beginning to think about A/C for the Bristol
