Hotter engine = better efficiencey. That's true. But i really doubt that efficiency was the mfg'ers goal at all.
Would the prewar engines hold up at a sustained 190 - 200 degree operating temperature assuming a pressurized cooling system was adapted at the time???? I doubt it. Not many prewar or even pre 1955 engines would run more than 50k miles without piston ring replacement.
SO the efficiency of the post war hotter engine was more or less a positive unintentional side effect of the cheaper radiator combined with technology that stemmed out of WWII.
