Thank you fellas from your input. Looks like I'm going to get the 180 deg stat. I know with the airplane, it was imperative that you get the oil temp over 180 degrees to burn off all the combustion crap that accumulates. Since I do drive it in cooler weather, and don't drive it when it's screaming hot, I think 180 is the way to go. Thanks for the heads up on the fitment.
