I am pulling my hair out over this. The car can sit and idle in the driveway for 20 minutes and never get higher than 180*. I can then take it out on a long drive and still never gets over 180*. But if I allow it to get to 180* and then shut the car off which naturally causes a spike in temp usually to about 210 the cooling system will not recover once I crank it up again. After cranking it up again and taking it down the road it will maintain the 210 but if I get into traffic or have to stop at a light it will spike again as high as 250 and will barely go down from there. I am running a Dewitt's BB aluminum radiator with dual spal's set at 160* for low and 190* for high. Fluid is 70/30 water to antifreeze with a bottle of water wetter. Stat has been changed twice now running a Mr Gasket HP stat which I tested before I installed it. Ignition is @ 18* adv at idle and 36* all in @ 3000. Carb is set pretty close and may even be a littl on the rich side still. I have been told that the Victor series H2O pumps need higher rpms to ncrease flow. Is it possible that the pump is not flowing enough at the low rpms?
