| Brief History: | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Whilst the original concept may have perhaps gone back to Columbo it was Tadaeucci who supervised the engine development. Utilising the experience with the 4 cylinder 150S and 200S similar relative dimensions to the 150S were used. Colotti had the task of ensuring the 400 bhp could get to the ground and this was achieved by the transmission, with the 5-speed gearbox in unit with the ZF self-blocking differential being carried within the wheelbase in a longitudinal position so as to not overload the rear axle - a problem encountered on the 350S. The frame was a relative of the 300S and was influenced by the 350S. The first engine was mounted on the original 350S frame in 1956, but the car did not compete until 1957 in Buenos Aires with a new body and frame, and following a change in the engine firing order which eliminated major vibrations. It was competitive throughout the 1957 year. At Le Mans in that year it appeared in a special body designed by Frank Costin and built hurriedly by Zagato. For that event and the Mille Miglia a two speed supplementary transmission was used with an overdrive function. Outlawed by the 3.0 litre rule in 1958 the car went on to great success in the US and in the marine use of the engine. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||
