Ford introduces the flathead V8 engine.
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.
