Running hot
I have a stock 1966 22" radiator in my 1966 Valiant, had it recored with a "high flow" efficiency 2 core, it flows the same as a 3 core. My car runs at 180 all day long, rarely ever going above 190! I use a steel factory fan shroud, 180 thermostat, Flowkooler high flow water pump, and a stock 4 blade fan and pullies, just plain antifreeze, no additives. I have a 340 in my car, more info about can be seen in my profile garage if needed. Here are a couple of pics....
