Bizzarrini seemed to be fired by Ferrari during the "palace revolt" of 1961.

Serenissima.One of ATS's fiscal backers, Count Giovanni Volpi, owner of Scuderia Serenissima, hired Bizzarrini to update 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 also called the "Breadvan".Bizzarrini's engineering company, Societa Autostar, was commissioned to design a V-12 engine for the GT car to become built by another dissatisfied Ferrari customer, Ferruccio Lamborghini. Lamborghini considered the resulting engine to become too highly strung, and ordered that the idea be detuned.

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 formulate a pressed steel figure chassis for Iso automobiles. Renzo Rivolta hired him as consultant for the Iso Gordon GT project which became the Iso Rivolta GT. The Iso Gordon GT prototype got its start from the Gordon-Keeble. The Gordon Keeble GT had been designed in 1960 by simply Giugiaro. Bizzarrini tested the vehicle and was impressed because of the powerful V8 Corvette engine plus the rear De Dion tube used for the GT:'Rivolta received me test the prototype. I liked its De Dion tubing and especially the Corvette serps. It was the first time I had driven 1. It was superior to Ferrari's engines, having the same power but having a more immediate throttle answer. 'The Iso Rivolta GT was a Giugiaro designed four seater with beautiful physique, speed, comfort and handling, and was a prosperous car for ISO with 799 units sold. Powered by a 327ci Chevrolet Corvette V8 engine with a classic De Dion raise suspension design with constrained steel monocoque bodywork more than pressed steel frame chassis.

Later versions of the particular Grifo were powered by way of a big block Chevrolet Corvette 435 bhp (324 kW; 441 PS) serps. These 90 handbuilt units are distinguishable with the raised "pagoda style" scoop bonnet. Some of these Iso Grifo 7 Litri items were rebuilt later with even bigger engines.

The thought of Bizzarrini was to use the 3AL cars for competition. The competition versions on the Grifo were named Iso Grifo A3C, C for Competizione or maybe Corsa. A new lightweight riveted alloy body was designed along with built by Piero Drogo. It was an aggressively designed machine, oriented to endurance backrounds. It uses normal ISO underpinnings but the engine was moved further the government financial aid the chassis frame compared to Grifo A3L, protruding well into the particular driver's cabin, fitted with hot cams and fed by some big Weber carburettors, giving more than 500 bhp (298 kW; 406 PS).

All around 29 A3C sport cars were built beneath the ISO name. Five of these 28 cars were bodied inside plastic/fiberglass by Piero Drogo from Carrozzeria Sports Cars with Modena. A3Cs were widely ran. Some cars entered the actual 1964 and 1965 The Mans 24 hour, 1965 Nürburgring 1000 along with 1965 Sebring. It achieved a Le Mans class win in both years along with a 9th overall in 1965 without the need of factory support. A3Cs were one in the fastest cars on LeMans' Mulsanne Right in both years.
