The seems to adjust up and down pretty quick. When it hit 210 I was getting on it much more then usually and it took maybe 3 minutes to come down to between 200-205. I can see the temp raise if I nail it for say 30 seconds... But everything seems fine. The engine runs great. The timing is by ear (the car has a small cam). The carb could be adjust a little better probably a little rich I moved the car from 900 feet in Kentucky to 5400 here in NW Colorado. But I'm not sure it was adjust right in ky either...

I just wanted to check and see the consenus of the group of proper running temp. And is the 190 degree verses the 165 degree I have surprizes me.. I would think the 165 would help control the over all flow..

Thanks... Over the years this forum has been a wonderful resource...
