Finally solved my over heating problem!!!

In Smokey Yunick's book; POWER SECRETS,(originally published 1983) he talks about running his Chevy powered cars at up to 220*, as being normal for his cars, as measured where the water returns to the top of the rad.He then goes on to recommend a normal operating range of 200 to 210, and 200 as a minimum. He alsorecommends a minimum oil temp of 230, and an operating range of 230 to 260, with the 260 being the safe upper limit. And a little research indicates 285 is the typical oil-breakdown temp,and is also mentioned in his book.
I run a 195* stat that actually returns water at those 200 to 210 levels. I suppose it's defective.. But hey, of all the used 195 stats I tested, this one ran the hottest minimum temp, so in it went.Then I added a 7-qt roadrace pan to help keep the oil temps up/down, in which I only run 5 to 5.5qts. I incorporated many of his ideas into my project, and have never been sorry.
So there you have it. If you want to make power, run the water up to 210, and the oil up to 245.Seems to work for me.
BTW; 220 to 230 just happens to be the set points of a lot of, if not most of, modern cooling system electric fans, as found on most sub 4liter engines. Maybe the factory engineers actually got something right. Hmmmmmm.
