Re: How hot can you really run a flathead safely?
High flow pumps are not nessarly a good thing in a pre 37 motor because it creates a low pressure zone in the block . on post 36 its a different story because its pushing water so you can get a high pressure zone in the block providing you have a restriction on the out side eg Thermostats therby lowering the boiling point .This is what Ford Engineer Emile Zorrline was striving for when he moved the pumps in 37,
