Many changes were made to the A3/L to create the A3/C, the car was given an entirely new body, the engine was moved back for better weight distribution, and the final production car weighed in at less than 2,200 lbs (1,000 kgs). The car was developed by a veritable dream team, the body was designed by Giorgetto Giugiaro, the engineering was done by Giotto Bizzarrini, the car was built by Piero Drogo, and it was powered by a modified 5.4 liter Chevrolet small block 327 V8 engine. The Iso Grifo A3/C was developed on the Iso Grifo A3/L for racing, specifically to compete at the 24 Hours of Le Mans and other similar endurance events. Relatively few were made, and after Bizzarrini left Iso he created his own company specifically to build more examples of the A3/C.
With all of this in mind, it’s a surprise that the Iso Grifo A3/C isn’t considerably more famous than it is.
The Iso Grifo A3/C was developed by Giotto Bizzarrini as the high-performance, racing version of the road-going Iso Grifo A3/L. Bizzarrini had earlier developed the legendary Ferrari 250 GTO, he said that the Iso Grifo A3/C was intended as a direct successor to the Ferrari.
