Iso Rivolta was the brainchild of Italian Engineer Renzo Rivolta who had been responsible for Isothermos refrigeration units prior to World War 2.
Wishing to move into motorised transport markets Rivolta developed a range of expensive but well built durable motorcycles from 1948 to 1961.
In 1950’s Renzo developed his best known vehicle the Isetta Bubble Car that was manufactured by Iso in Italy and under licence by Velam in France, Romi in Brazil and most successfully by BMW in Germany.
After leaving Ferrari in 1961, where he had been responsible for the fabled Ferrari 250 GTO, Giotto Bizzarrini set up his own design studio and in 1963 designed the mechanical architecture of the Iso Griffo A3/L. The Grifo,launched in 1963, featured a blueprinted, a process of disassembling a motor then rebuilding it with all the engine parts matching the exact original engine blueprint design specifications for optimal performance, 400 horsepower small block Chevrolet motor.
In 1968 the Grifo was made available with a 435 hp Chevrolet 427 big block motor, requiring the pagoda like air scoop on the bonnet to accommodate the extra height of the larger engine,
along with extra ventilation in the front wings to keep the motor cool, seen on this vehicle which was built in 1969.
The Grifo 7 Litri was said to be capable of 186 mph.
It would appear that just 67 of the 7 Litri Series I vehicles were produced from 1968 to 1970 when the rarer Series II Grifo’s with pop up head light covers were introduced.
The combination of rarity, Bertone styled beauty and mechanical simplicity, a result of using many proprietary parts including the engine and gearbox, makes the Grifo a relatively easy to maintain collectible car.
