His father was any rich landowner who came from a family with sturdy roots in Tuscany plus the city of Livorno. His grandfather, also named Giotto Bizzarrini, was a biologist who had worked with Guglielmo Marconi on his inventions, especially the radio, following which one of the Livorno Library sections had been named The Bizzarrini Catalogue.Bizzarrini graduated as an engineer in the University of Pisa inside 1953.

Serenissima.One of ATS's financial backers, Count Giovanni Volpi, owner of Scuderia Serenissima, hired Bizzarrini to update a Ferrari 250 GT SWB, with chassis number #2819GT to help GTO specifications. This resulted in the Ferrari 250 GT SWB Drogo also called the "Breadvan".Bizzarrini's engineering company, Societa Autostar, was commissioned to style a V-12 engine to get a GT car to always be built by another unhappy Ferrari customer, Ferruccio Lamborghini. Lamborghini considered the resulting engine to become too highly strung, and ordered that the item be detuned.

Bizzarrini worked since 1964 for Iso Rivolta and formulated three models: Iso Rivolta GT, Iso Grifo both A3L as well as A3C versions. His work was in order to develop a pressed steel framework chassis for Iso cars. Renzo Rivolta hired him as consultant to the Iso Gordon GT undertaking which became the Iso Rivolta GT. The Iso Gordon GT prototype originated from the Gordon-Keeble. The Gordon Keeble GT ended up being designed in 1960 through Giugiaro. Bizzarrini tested the car or truck and was impressed with the powerful V8 Corvette engine along with the rear De Dion tube used for the GT:'Rivolta acquired me test the prototype. I liked its De Dion pipe and especially the Corvette serps. It was the very first time that I had driven one particular. It was superior to Ferrari's engines, having the same power but using a more immediate throttle result. 'The Iso Rivolta GT had been a Giugiaro designed some seater with beautiful system, speed, comfort and handling, and was a prosperous car for ISO using 799 units sold. Powered by a 327ci Chevrolet Corvette V8 engine that has a classic De Dion rear suspension design with pressed steel monocoque bodywork more than pressed steel frame chassis. Unveiled to the mass media in 1963, production continued until 1970.The Iso Grifo A3L has been a monstrous idea to get a super coupé, the L coming through Lusso. The result of the actual brilliant Giugiaro and Bizzarrini functioning together, it was based over a shortened Iso Rivolta GT framework and was debuted at the 1963 Turin show. The Grifo epitomised the particular 1960s Italian style having its handsome low and vast handmade bodywork. It was the most effective production car tested by Autocar Magazine in 1966 using a top speed of one hundred sixty mph (260 km/h). Later versions of the particular Grifo were powered by the big block Chevrolet Corvette 435 bhp (324 kW; 441 PS) engine. These 90 handbuilt units are distinguishable through the raised "pagoda style" deal bonnet. Some of these Iso Grifo 7 Litri items were rebuilt later with even bigger engines.

The concept of Bizzarrini was to utilize 3AL cars for opposition. The competition versions on the Grifo were named Iso Grifo A3C, C for Competizione as well as Corsa. A new lightweight riveted aluminium body was designed as well as built by Piero Drogo. It was an strongly designed machine, oriented to endurance backrounds. It uses normal ISO underpinnings though the engine was moved further back in the chassis frame as opposed to Grifo A3L, protruding well into your driver's cabin, fitted with hot cameras and fed by 4 big Weber carburettors, giving more than 300 bhp (298 kW; 406 PS).

All around 29 A3C sport cars were built beneath the ISO name. Five of these 30 cars were bodied within plastic/fiberglass by Piero Drogo at Carrozzeria Sports Cars in Modena. A3Cs were widely raced. Some cars entered the 1964 and 1965 Le Mans 24 hour, 1965 Nürburgring 1000 along with 1965 Sebring. It achieved a Le Mans class win in both years as well as a 9th overall in 1965 without having factory support. A3Cs were one on the fastest cars on LeMans' Mulsanne Right in both years.
