Under Danny's leadership, for the first time, Ford topped NASCAR's point standing in 1956. But almost at the same time Danny wanted to show Fords were not only fast but reliable. Using two identical '56 Fords traveling for 24 hours around the Indianapolis Motor Speedway, Danny set an endurance record of 107 mph, including fuel stops: "We drove two identical cars around the Speedway-in case one failed, we could keep the record attempt going. Johnny Mantz and Chuck Stevenson drove one and Chuck Diegh and I drove the other. We started the Fords both at the same time to keep things legitimate."
