Before I had to change the water pump out the car with the rad. would run about half way on the gauge. Than sitting in traffic u would see it start going up if u didn't get the car moving. But now with the mod. to the water pump and the rad. it stays at around 1/4 on the gauge. So I have been trying to do some tuning on the engine with the timing and carb. adjusting its coming around little by little. It runs 80% better than when I 1st got the car from how it ran. I think It maybe a 180 in there I'll have to pull it down and see.
