Running hot

I am having pretty much the same trouble. I have put in a new water pump and an electric fan and have not had much luck. When I put the ne pump in I put in a 50/50 mix of fluid, maybe I should have flushed the system before I took the old pump off. Maybe I will have to make a trip to the radiator shop and have it worked on. It seemed to be OK last year but this spring we put the 4 barrel on the 318 to give it a little more PEP.8)

At least I know more guys have the same issue and now I know the next step to take.
