This resulted in this Ferrari 250 GT SWB Drogo generally known as the "Breadvan".Bizzarrini's engineering company, Societa Autostar, was commissioned to layout a V-12 engine for just a GT car to possibly be built by another discontented 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 regarding Iso Rivolta and created three models: Iso Rivolta GT, Iso Grifo both A3L along with A3C versions. His work was in order to develop a pressed steel body chassis for Iso vehicles. Renzo Rivolta hired him as consultant towards Iso Gordon GT task which became the Iso Rivolta GT. The Iso Gordon GT prototype originated from the Gordon-Keeble. The Gordon Keeble GT had been designed in 1960 simply by Giugiaro. Bizzarrini tested the auto and was impressed through the powerful V8 Corvette engine along with the rear De Dion tube for the GT:'Rivolta experienced me test the prototype. I liked its De Dion pipe and especially the Corvette serps. It was the very first time I had driven just one. It was superior to be able to Ferrari's engines, having the same power but which has a more immediate throttle reply. 'The Iso Rivolta GT was a Giugiaro designed some seater with beautiful entire body, speed, comfort and handling, and was a successful car for ISO using 799 units sold.

The thought of Bizzarrini was to utilize 3AL cars for competition. 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 and built by Piero Drogo. It was an strongly designed machine, oriented to endurance events. It uses normal ISO underpinnings though the engine was moved further last the chassis frame as opposed to Grifo A3L, protruding well into the driver's cabin, fitted with hot cameras and fed by a number of big Weber carburettors, giving more than four hundred bhp (298 kW; 406 PS).

All around 29 A3C sport cars were built underneath the ISO name. Five of these 29 cars were bodied in plastic/fiberglass by Piero Drogo with Carrozzeria Sports Cars in Modena. A3Cs were widely competed. Some cars entered your 1964 and 1965 Le Mans 24 hour, 1965 Nürburgring 1000 in addition to 1965 Sebring.
