Giotto Bizzarrini
Giotto Bizzarrini left Ferrari and joined the young team of Automobili Lamborghini in 1963. He designed and built the first legendary Lamborghini V12 engine. It did not take him much time to develop and finish this engine, which delivered an incredible 400 hp at 11000 rpm. However, Lamborghini wanted the engine to be suitable for a GT, so it was detuned to 280 hp at 7000 rpm. Bizzarrini disliked this, and left the company as soon as the engine testing was finished.
