The 501 reliability and strength were unchanged in the sport version too, and this was the basis for the car tuning. One of the most famous tuners was the Milanese technician Eugenio Silvani, who designed just for the 501 model a cylinder head modification with the conversion of the distribution from side valves to head valves. The famous "Superculasse Silvani" cylinder head was sold as a performing kit with all the gaskets, manifolds and valve shafts necessary for the fitting; it had a large diffusion thanks to its easy fitting. The "Superculasse Silvani" gave more power, acceleration and running flexibility to the engine.
The Fiat 501 S shown in the museum was apparently ordered by the Fiat agents in Bombay for the maharajah of Patiala and is fitted with the "Superculasse Silvani". The body has been rebuilt in the Seventies.
