I've done alot of driving in my time, drag racing, road racing, street racing, and daily driving. I love some of the input you get from people. I know what works, I don't have any of the problems that people talk about with running a 160 therm. If you noticed our engines turn less than 2,000 rpms on the hwy at 65. At those speeds our engine don't produce much heat. Now take the O/D off and drive on the hwy at 3,000 rpms or higher see how hot your temp rises. Even with the 160 I'm at 200 deg and it never goes below 180.
Yes I think I would have carbon buildup or other problems assocaited with running the engine cooler but I don't. If I didn't have winter where I live I'd have no thermastat and would run a restricter. Thank you HankL your info is very detailed right down to the valience electrons and protons. I'm not the smartest rocket scientist out there, but I know what I know.
