Thanks for the info Joe. I had read somewhere, that an extra 20- 30 degrees of coolant temperature over 212 in a Model A brings oil close to the flash point on the cylinder walls. So you really do not want to go over that temp.

You were comparing a modern 15 PSI to a model A. Am curious, do you really gain much at less than 4 PSI, which I believe what most Model A pressurized systems run? Am asking because I do not know.

My opinion is that if a stock unpressurized A is regularly overheating at 212 water or antifreeze, something is not right and needs attention.

I agree with not using the stupid or similar remarks, if somebody (like myself) posts something incorrect, I appreciate being corrected and educated. I know I've probably learned a lot of things that are not correct by trying to sift through all the multiple and sometimes conflicting opinions. And is why I post a lot, to validate what I think I know.

As far as modified vs. stock - there is room for everyone to enjoy their A as they like and should not be criticized for their decisions.
