Doug,
Only mechanical related issue is that my car never got above 150 degrees water temp and that was idleing with no fan. Under road conditions mine would drop to 110-120 F water temp. This probably isn't good. I think by putting in the racing 170 degree thermostat with the bypass hole the water never slowed up enough to heat. We build these Texas cars to not get hot, didn't think about the winter issue. Well probably will NEVER have to worry about it again!!!
