Wont be much different than most said here, but i have a 427W and the
oil stays at an incredibly low temp....usually below 80C. So, I had a thermostat installed to make sure it stays open until approx 195C, but it hardly ever gets there regardless. I notice the car runs better with hotter
oil temp but ....it is what it is. My water temp rarely exceeds 195 either, but the fan hits on at that temp so all is good.
basically the car runs cool vs hot and never have any issues.
