This resulted in this Ferrari 250 GT SWB Drogo also known as the "Breadvan".Bizzarrini's engineering company, Societa Autostar, was commissioned to design a V-12 engine to get a GT car to always be built by another unhappy Ferrari customer, Ferruccio Lamborghini.

Bizzarrini worked since 1964 regarding Iso Rivolta and designed three models: Iso Rivolta GT, Iso Grifo both A3L in addition to A3C versions. His work was to develop a pressed steel shape chassis for Iso cars and trucks. Renzo Rivolta hired him as consultant on the Iso Gordon GT challenge which became the Iso Rivolta GT. The Iso Gordon GT prototype was made from the Gordon-Keeble. The Gordon Keeble GT ended up being designed in 1960 through Giugiaro. Bizzarrini tested the automobile and was impressed by the powerful V8 Corvette engine plus the rear De Dion tube used by the GT:'Rivolta had me test the prototype. I liked its De Dion tubing and especially the Corvette serps. It was the very first time I had driven one. It was superior to help Ferrari's engines, having the same power but using a more immediate throttle answer. 'The Iso Rivolta GT has been a Giugiaro designed four seater with beautiful system, speed, comfort and handling, and was a prosperous car for ISO with 799 units sold. Powered by a 327ci Chevrolet Corvette V8 engine that has a classic De Dion backside suspension design with constrained steel monocoque bodywork over pressed steel frame chassis. Unveiled to the press in 1963, production continued until 1970.The Iso Grifo A3L has been a monstrous idea for any super coupé, the L coming via Lusso. The result of this brilliant Giugiaro and Bizzarrini working together, it was based with a shortened Iso Rivolta GT chassis and was debuted on the 1963 Turin show. The Grifo epitomised this 1960s Italian style with its handsome low and large handmade bodywork. It was the speediest production car tested by Autocar Magazine in 1966 that has a top speed of 160 mph (260 km/h). Later versions of the actual Grifo were powered with a big block Chevrolet Corvette 435 bhp (324 kW; 441 PS) engine. These 90 handbuilt units are distinguishable with the raised "pagoda style" details bonnet. Some of these Iso Grifo 7 Litri devices were rebuilt later with a whole lot larger engines.

The concept of Bizzarrini was to operate the 3AL cars for competitors. The competition versions from the Grifo were named Iso Grifo A3C, C for Competizione or perhaps 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 backrounds. It uses normal ISO underpinnings however the engine was moved further last the chassis frame compared to Grifo A3L, protruding well into the actual driver's cabin, fitted with hot cameras and fed by some big Weber carburettors, giving more than 600 bhp (298 kW; 406 PS).

About 29 A3C sport cars were built under the ISO name. Five of these 28 cars were bodied inside plastic/fiberglass by Piero Drogo on Carrozzeria Sports Cars with Modena. A3Cs were widely raced. Some cars entered this 1964 and 1965 Le Mans 24 hour, 1965 Nürburgring 1000 and also 1965 Sebring. It achieved a The Mans class win in both years and a 9th overall in 1965 without any factory support. A3Cs were one with the fastest cars on LeMans' Mulsanne Straight in both years.
