My first exposure to the education on Windage was an engineering article written by Zora Arkus Duntov in about 1957, I think . . He stated that with an adequate Oil Pump, and no windage control, a SBC sould run out of oil in the pan in less than a mile at 7000 RPM . .
And then went on to explain the various ways windage saps Horsepower from the rotating assembly. To a novice Car Nut it was almost frightening. But it certainly started me off right . .
