Lamborghini 350 GT - The engine goes into series production and reaches more than 250 km/h

Paolo Stanzani, one of Lamborghini's most respected engineers, was then tasked with 'cultivating' the engine. His modifications preserved the engine's exceptional performance but made it more drivable at medium and low revs. The basic technical features remained unchanged, which in many respects represented an absolute premiere for a series-produced vehicle. The maximum output of 280 hp at 6500 rpm was enough to propel the 350 GT, Lamborghini's first production model from 1964, to a top speed of over 250 km/h
