1964 Bizzarrini Iso Grifo A3/C Berlinetta

Giotto Bizzarrini worked with Alfa Romeo and Ferrari on the development of their cars. In 1962 he founded his own company, Autostar, in Livorno, Italy, and went on to work with Renzo Rivolta, producing the Iso Rivolta and Iso Grifo A3C models. The company was renamed Prototipi Bizzarrini and produced several Bizzarrini models including the 5300 Corsa, which was also on display at the 2007 Pebble Beach Concours d'Elegance. It is one of the three chassis built by the factory that year. This car is described by Sports Car Graphic magazine as 'a cross between a Sting Ray Corvette and a Ferrari GTO.' The 5300 Corsa has the Iso Grifo A3C body, a chassis powered by a 327 Corvette motor and is badged as a Bizzarrini.

The Bizzarrini Corsa was specially made by Giotto Bizzarrini, one of the most prolific auto designers of the 1960s. After receiving a degree in mechanical engineering from the University of Pisa in 1953, Bizzarrini went to work for Alfa Romeo but later moved on to Ferrari, where he created the celebrated GTO racing coupe. He struck out on his own in 1961 as a consultant, building the chassis of the Iso Grifo and designing the chassis and V12 engine for the Lamborghini 350 GT. Next, he arranged to build a version of the Grifo under his own name. This was a two-door coupe, equipped with a Chevrolet V8 engine. It was imported into the United States in time for the 1964 Sebring 12-hour enduro. It placed 39th overall and 12th in class. It was an SCCA Championship car in 1964, with Ed Hugus driving.
