GM got sued by Evans over the rights to the "Reverse Flow Cooling system"
http://money.cnn.com/magazines/fsb/f...3431/index.htm
And according to the diagram below & everything else ive read....Your right.
BUT...There is a BIG problem with this diagram! It shows the coolant from the radiator flowing through thermostat into the engine. How would that work? The cooler water from the radiator would close the thermostat before all the hot water got out of the engine. If we reverse the flow on the diagram...It would be a perfect example of a "Reverse flow Cooling System" & the thermostat would work like every other thermostat Ive ever seen.
My theory is LS engine are reverse flow...Untill someone explains how a thermostat can operate on the suction side of a cooling system, I stand by what I stated earlier.
