As with the new Model A, Henry Ford shut down all other production operations to work on this innovative project. At great effort and expense, the company engineered a way to cast the first commercially successful V8 engine. The flathead was a hit. It was affordable, versatile, and introduced just as the American market was becoming fascinated with ever-more powerful engines. It remained in production for over 22 years. To this day the flathead remains extremely popular with hot rodders.
