If your 350 is running around 215,dont worry about it.they tend to run on the hot side.Also if you are running a fan shroud there is no reason for an electric fan.I have to laugh at the strret rods set up with the fan about 6 inches from the radiator and yeah there is an electric fan.A good shroud would do twice as much good,as it makes the fan pull air thru the radiator.
