the only NASCAR race with no winner, The Myers Brothers 250 at Bowman Gray Stadium, August 6, 1971. Bobby Allison won't get credit from Nascar, because his Mustang was a GA car, Nascar did not credit him, or anyone else with the GN win.

Bobby Allison won the race at Bowman Gray after taking the lead shortly before halfway. The 2011 inductee drove the No. 49 Coca-Cola Ford Mustang, a Grand American car. He took the lead from Richard Petty’s Plymouth. Petty was the highest finishing Cup car in second, the only other car on the lead lap.

Meanwhile, for the Bowman Gray race, should Allison’s win stand solely as a class win, seven-time Cup Series champion Petty would shift from 200 to 201 victories based on NASCAR’s precedent in other regional series. That would dramatically change the significance of several races, including what is currently accepted as ‘The King’s 200th victory in the 1984 Firecracker 400.

For Allison, who to this day maintains he won that Cup race in 1971, the additional win would break a long-standing tie with fellow Hall of Famer Darrell Waltrip. Allison would move to having sole possession of fourth on the all-time NASCAR Cup Series win list.
