Engine Temperature

My brother has a Class A Chevy P30 chassis motorhome with a 454 and needs to know what is the normal operating temperature while on the road? When he's running around 55-60 MPH, the temperature runs between 195-200 degrees. If he pushes the speed to 65, the temperature goes up to 210 degrees. Are these normal?

Hi Mike,
Are you losing water? This temperature is about normal if it is a late model 454. You might want to check the ignition timing, clutch fan and clean any bugs, debre from the fins in the radiator. Also check the radiator cap.
