The format for IROC
6 was different, with special qualifying races staged for the NASCAR,
Indy Car and road racing drivers, and the first four finishers in each
advanced to two final contests. The road racing finale was a heartbreaker
for Gordon Johncock. He led from the start, only to spin just three
laps from the finish after a yellow flag for oil from Al Unser's blown
engine. Mario Andretti inherited the lead and the victory. In the oval
track finale at Atlanta, Andretti led until the last three laps, when
Cale Yarborough nudged him out of the groove, and Neil Bonnett took
the lead. A four-car photo finish saw Bonnett take the checkered flag
by half-a-fender over Andretti. Bobby Allison just nipped Yarborough
for third in between Andretti and Bonnett. Al Unser lost control late
in the event and was tagged by Johncock. His first-second finishes in
the road course and oval finals gave Andretti the IROC title. (from
