I was told you cannot fit the clutch fan along with a 4 core unit, when using long w/pump ,so was hoping the 3 core will be sufficient is all
Thanks

As Sully mentioned the stock setup works pretty well in most cases. The clutch fan vesion will not work with the long water pump, regardless if it is 3 or 4 core. You didn't mention what year Nova we are discussing...but, the 68 BB Nova [short water pump] did use the clutch fan setup, so if you want to mimic that arrangement it is possible. BB cooling issues typically come from an improper thermostat, bad pump, incorrect timing or a radiator that has issues.
