Bizzarrini had been fired by Ferrari throughout the "palace revolt" of 1961. He became part connected with Automobili Turismo e Activity (ATS)), a company started with the ex-Ferrari engineers to make a Formula 1 single seater along with a GT sport car, the A. T. S. Serenissima.One of ATS's financial backers, Count Giovanni Volpi, owner of Scuderia Serenissima, hired Bizzarrini to up grade a Ferrari 250 GT SWB, with chassis number #2819GT for you to GTO specifications. This resulted in the 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 to get a GT car to become built by another discontented Ferrari customer, Ferruccio Lamborghini. Lamborghini considered the resulting engine being too highly strung, and ordered that that be detuned.

Bizzarrini worked since 1964 intended for Iso Rivolta and produced three models: Iso Rivolta GT, Iso Grifo both A3L in addition to A3C versions. His work was to produce a pressed steel framework chassis for Iso cars. Renzo Rivolta hired him as consultant for the Iso Gordon GT undertaking which became the Iso Rivolta GT. The Iso Gordon GT prototype was developed from the Gordon-Keeble. The Gordon Keeble GT ended up being designed in 1960 simply by Giugiaro. Bizzarrini tested the car and was impressed from 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 tubing and especially the Corvette engine. It was the first time I had driven just one. It was superior for you to Ferrari's engines, having the same power but which has a more immediate throttle result. 'The Iso Rivolta GT seemed to be 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 that has a classic De Dion backed suspension design with constrained steel monocoque bodywork more than pressed steel frame chassis. Unveiled to the media in 1963, production continued until 1970.The Iso Grifo A3L had been a monstrous idea for a super coupé, the L coming coming from Lusso. The result of the particular brilliant Giugiaro and Bizzarrini working together, it was based on a shortened Iso Rivolta GT chassis and was debuted for the 1963 Turin show. The Grifo epitomised your 1960s Italian style having its handsome low and vast handmade bodywork. It was the quickest production car tested by means of Autocar Magazine in 1966 with a top speed of 160 mph (260 km/h). Later versions of the actual Grifo were powered by way of a big block Chevrolet Corvette 435 bhp (324 kW; 441 PS) serp. These 90 handbuilt units are distinguishable with the raised "pagoda style" information bonnet. Some of these Iso Grifo 7 Litri models were rebuilt later with a whole lot larger engines.

The idea of Bizzarrini was to use the 3AL cars for levels of competition. The competition versions from the Grifo were named Iso Grifo A3C, C for Competizione as well as Corsa. A new lightweight riveted aluminum body was designed and also built by Piero Drogo. It was an in a hostile manner designed machine, oriented to endurance events. It uses normal ISO underpinnings even so the engine was moved further in the chassis frame as opposed to Grifo A3L, protruding well into this driver's cabin, fitted with hot cams and fed by four big Weber carburettors, giving more than 400 bhp (298 kW; 406 PS).

Around 29 A3C sport cars were built under the ISO name. Five of these 30 cars were bodied with plastic/fiberglass by Piero Drogo from Carrozzeria Sports Cars in Modena. A3Cs were widely competed. Some cars entered the 1964 and 1965 The Mans 24 hour, 1965 Nürburgring 1000 and also 1965 Sebring. It achieved a Le Mans class win in both years and a 9th overall in 1965 with no factory support. A3Cs were one on the fastest cars on LeMans' Mulsanne Right in both years.
