Finally got back to work on my 500 swap and got it running. It will run 190 degrees all day idling in my driveway and around town. At that temp it will spin the tires all the way through second gear. It runs closer to 210 on the highway and when I get off the highway it turns into a dog. Won’t even spin the tires anymore. Part throttle driveability is not compromised. The only modifications are a 2115 intake, Holley 750 vac secondary, and headers. Factory 4 core BB radiator, brand new water pump, and 180 deg t-stat, Ford windstar electric fan-on at 190, off at 180. I’m not sure what temp range these things ran at from the factory , but I have a hard time believing they didn’t occasionally get to 210. Any and all help is appreciated.
