Bizzarrini ended up being fired by Ferrari in the "palace revolt" of 1961.

Serenissima.One of ATS's personal backers, Count Giovanni Volpi, owner of Scuderia Serenissima, hired Bizzarrini to up grade a Ferrari 250 GT SWB, with chassis number #2819GT to be able to GTO specifications. This resulted in the particular Ferrari 250 GT SWB Drogo often known as the "Breadvan".Bizzarrini's engineering company, Societa Autostar, was commissioned to design and style a V-12 engine for any GT car to always be built by another not satisfied Ferrari customer, Ferruccio Lamborghini.

Bizzarrini worked since 1964 regarding Iso Rivolta and developed three models: Iso Rivolta GT, Iso Grifo both A3L in addition to A3C versions. His work was to formulate a pressed steel shape chassis for Iso cars and trucks. Renzo Rivolta hired him as consultant towards Iso Gordon GT project which became the Iso Rivolta GT. The Iso Gordon GT prototype was developed from the Gordon-Keeble. The Gordon Keeble GT was designed in 1960 through Giugiaro. Bizzarrini tested the vehicle and was impressed by the powerful V8 Corvette engine plus the rear De Dion tube employed for the GT:'Rivolta had me test the prototype. I liked its De Dion pipe and especially the Corvette serp. It was the first-time I had driven a single. It was superior to help Ferrari's engines, having the same power but with a more immediate throttle reply. 'The Iso Rivolta GT was a Giugiaro designed some seater with beautiful system, speed, comfort and handling, and was a productive car for ISO along with 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 above pressed steel frame chassis. Unveiled to the press in 1963, production continued until 1970.The Iso Grifo A3L was a monstrous idea for any super coupé, the L coming coming from Lusso. The result of the actual brilliant Giugiaro and Bizzarrini doing work together, it was based on a shortened Iso Rivolta GT chassis and was debuted on the 1963 Turin show. The Grifo epitomised this 1960s Italian style featuring a handsome low and large handmade bodywork. It was the fastest production car tested through Autocar Magazine in 1966 that has a top speed of 160 mph (260 km/h). Later versions of this Grifo were powered by way of a big block Chevrolet Corvette 435 bhp (324 kW; 441 PS) serp. These 90 handbuilt units are distinguishable from the raised "pagoda style" deal bonnet. Some of these Iso Grifo 7 Litri models were rebuilt later with even bigger engines.

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