"This looks like Stewart's Cortina leading the Barracuda of Scott Harvey and Les Netherton (owner of the track) and another Cortina. It has to be early in the race because Stewart had built up a 30 second lead by the time his motor seized after 30 minutes. Once Stewart dropped out, the Harvey/Netherton-driven Barracuda led the race for 7 hours until it dropped out with a broken axle."
