June of 1966 marked the first time an American manufacturer won the 24 Hours of Le Mans. With its massive 7.0L v-8, the Ford Gt40 howled through the Circuit de la Sarthe finishing 1st, 2nd, and 3rd. When Ford revealed the new Ford GT at Detroit people automatically jumped to assume a return to Le Mans; they were right. Obviously when transforming a production car into a race car there needs to be intense testing or shakedowns. These shakedowns are crucial for Ford engineers to dial in their race car, every inch of the GT is under a microscope. So when things go according to plan, only then were the engineers allowed to breath.
