383 is running hot. Not sure if the guage is faulty or if there's a problem. This weekend it went north of 220 then settled in at 215. Other days the thermostat seems to kick on and it stays about 190. Can a thermostat stick and not open sometimes? No overflow, no weird smell, no leakage that I can see- any thoughts?

not sure but when you open it up to check it out I would drill a small hole in the stat to let the air out, makes it alot easier when refilling coolant.

one way to know if Tstat is stuck is try to press the upper hose when hot. If is hard to pressure then Tstat is working propperlly or at least is opening

Thanks guys. I've never heard of drilling a hole in the Tstat.

1 more thing: If I replace the Tstat, should I go 180 or 160 degrees??? I know the 160 will kick on sooner, but is there anything else I should know?

is there any other way to tell if you have trapped air pockets? i'm having the same issue with my 383. i put a new 160 tstat in 2 weeks ago and she still runs anywhere from 220 to 200.
That's about where an engine runs. Todays cars run even hotter. That's why the system is pressurized, to raise the boiling point of water above 212°.

check your timming and check carb to make sure its not lean those will cause it to run hotter feel by hand the rad core when hot to see if you can feel cold spots on the rad...cold spots are where the rad is blocked do you have a spring in the lower hose? does it have the shrod in place? is the clutch fan working properly? yes a small hole will burp the air out and no need to run to temp and wait for the t stat to open to finish the fill try some water wetter in it also...

there was a very comprehensive thread recently with over 125 posts on an individuals overheating problem.Dont know if it could be retrieved or not. If so it might be worth reading for you.

Update- I changed the stock 195 tstat to a 180 tstat. When the guage reads 180-190 it kicks on and goes down. Just as the 195 did around 200. But then the same thing happened: it creeps up past 180 (195 before) and keeps going. Now it settles in around 205 until I stop at a light. Then it goes up very quickly to 220. That can't be good.
I do not have a shroud. Could that be the answer? I'll search for the other thread mentioned.
