The Iso Grifo is a limited production grand tourer automobile manufactured by Italian Iso Autoveicoli S.p.A. between 1965 and 1974. Intended to compete with Ferrari and Maserati GTs, it utilized a series of American power trains and components supplied by Chevrolet and Ford to ensure performance and maximize reliability. Styling was done by Giorgetto Giugiaro at Bertone, while the mechanicals were the work of Giotto Bizzarrini.
The first production GL models appeared in 1965 and were powered by American Chevrolet Corvette small-block 327 (5.4-litre) V8s fitted to American supplied Borg-Warner 4-speed manual transmissions. The 5.4-litre engine developed 300 hp (220 kW) in its standard form and could reach 110 km/h (68 mph) in first gear.
In 1970, a styling change was made to the nose section of the car for the Grifo Series II, It got a sleeker look and hide-away headlights. In the IR-9 “Can Am” version the engine was switched from the 427 engines to the newer even more powerful Chevrolet 454 7.4 litre engine.
