Hi, I think I have exhausted everything I can think of, I've messed with Fords all my life (I'm 59) and this one has me. It was fine until I changed the cam. Now when I'm over 60 mph it starts to overheat. The gauge never gets to "H" but it gets pretty close. The faster I go the hotter it gets. I've had the radiator flushed, watched the coolant flow well in the radiator. I have not changed the water pump but it is not leaking and does flow well, also new thermostat. What am I missing?
Thanks
Thanks
