What cooling systems are you guys running?

The old thermostat had some seaweed looking crud in it so I replaced it. Still overheats so I'm going to try some additional air movement with a big fan to see what happens.

Any other suggestions?

Get as big a fan as will fit on the radiator. Look for a Lincoln MkVIII unit (these are pullers)in the wrecking yards or an aftermarket unit. You need A LOT more air and maybe more radiator too. But start with the fan and a thermostat controlled on/off switch. Make sure you have ALL of the air out of the cooling system, make sure it is full of coolant, try adding "water wetter" too.
