Bizzarrini worked since 1964 regarding Iso Rivolta and developed three models: Iso Rivolta GT, Iso Grifo both A3L as well as A3C versions. His work was to develop a pressed steel frame chassis for Iso cars. Renzo Rivolta hired him as consultant to the Iso Gordon GT challenge which became the Iso Rivolta GT. The Iso Gordon GT prototype was created from the Gordon-Keeble. The Gordon Keeble GT had been designed in 1960 by means of Giugiaro. Bizzarrini tested the auto and was impressed through the powerful V8 Corvette engine as well as the rear De Dion tube for the GT:'Rivolta got me test the prototype. I liked its De Dion tv and especially the Corvette powerplant. It was the very first time I had driven a single. It was superior to Ferrari's engines, having the same power but with a more immediate throttle reaction. 'The Iso Rivolta GT has been a Giugiaro designed several seater with beautiful entire body, speed, comfort and handling, and was a productive car for ISO with 799 units sold. Powered by a 327ci Chevrolet Corvette V8 engine that has a classic De Dion back suspension design with pushed steel monocoque bodywork over pressed steel frame chassis. Unveiled to the click in 1963, production continued until 1970.The Iso Grifo A3L had been a monstrous idea to get a super coupé, the L coming coming from Lusso. The result of the actual brilliant Giugiaro and Bizzarrini operating together, it was based over a shortened Iso Rivolta GT framework and was debuted at the 1963 Turin show. The Grifo epitomised this 1960s Italian style featuring a handsome low and vast handmade bodywork. It was the speediest production car tested simply by Autocar Magazine in 1966 having a top speed of 160 mph (260 km/h). Later versions of the Grifo were powered by the big block Chevrolet Corvette 435 bhp (324 kW; 441 PS) powerplant. These 90 handbuilt units are distinguishable by the raised "pagoda style" deal bonnet. Some of these Iso Grifo 7 Litri products were rebuilt later with even bigger engines.

The concept of Bizzarrini was to utilize 3AL cars for rivalry. The competition versions from the Grifo were named Iso Grifo A3C, C for Competizione or even Corsa. A new lightweight riveted lightweight alloy body was designed and also built by Piero Drogo. It was an more boldly 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 4 big Weber carburettors, giving more than 600 bhp (298 kW; 406 PS).

The second car is listed as an “Iso A3C 1965 Competition” and is

All-around 29 A3C sport cars were built within the ISO name. Five of these 29 cars were bodied within plastic/fiberglass by Piero Drogo with Carrozzeria Sports Cars with Modena. A3Cs were widely raced. 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 plus a 9th overall in 1965 without factory support. A3Cs were one from the fastest cars on LeMans' Mulsanne Straight in both years.
