But Richard Petty, who was out of the points because of a shoulder injury suffered at Darlington in May, was considered the favorite to win the race.

Isaac, in the Nord Krauskopf's K&K Insurance Dodge, led 179 laps and took the win by six car lengths over Petty.

Isaac advanced to become the 1970 Winston Cup Champion at season's end, with Allison being the runner-up in points.

Tiny Lund, driving a 1970 Camaro, qualified sixth and led just seven laps on his way to the victory.

Dave Marcis finished fourth, two laps down, and Benny Parsons rounded out the top five.

Bobby Allison was the only other driver to lead, running 11 laps out front before losing an engine prior to the half.

Richard Petty and Bobby Allison swapped the lead for the rest of the race, beating and banging each other for the win.
