The thinking behind Bizzarrini was to make use of the 3AL cars for opposition. The competition versions in the Grifo were named Iso Grifo A3C, C for Competizione as well as Corsa. A new lightweight riveted alloy body was designed as well as built by Piero Drogo. It was an aggressively designed machine, oriented to endurance backgrounds. It uses normal ISO underpinnings but the engine was moved further back in the chassis frame compared to the Grifo A3L, protruding well into this driver's cabin, fitted with hot cams and fed by some big Weber carburettors, giving more than 300 bhp (298 kW; 406 PS).
