I have to agree that 10 degrees at idle was usually the stock settings,i think mine is at 13 or 14 at idle and at about 35 degrees full advance.id hook up a temp gauge and then you can see actual temperature
Do you have "The rest of the story"? Just wondering if you solved your problem, as these overheating problems keep popping up with various members. Thanks. MD
I added a temp gauge and discovered car was getting to 230 before I would get off highway. I bled the cooling system but have not had a chance to test. I am focused on finishing my 1970 Mach 1 restore at moment. I will provide update when I have one.
