The Ford Barn - View Single Post - Engine temp rises when I get to cruise speed

Any chance you are seeping combustion chamber gas into the coolant? I’ve always suspected this in my 51 stock system because it will climb at idle and 3000 rpm cruise. I added an overdrive years ago and it no longer heats up in the highway (~2000 rpm now). Ken
