The Grifo was designed by Bertone with the help of Giorgio Giugiaro and initially used Chevrolet’s 327-cubic-inch V-8 engine. Later models, including the one being offered, were powered by the iconic 427-cubic-inch V-8 engine, also known as the 7-Litri.
This engine had gained notoriety by powering Corvette race cars, and Iso claimed their 7-liter Grifos could reach speeds of up to 186 mph, making them highly desirable when new and still desirable today despite being limited in production.
