In the inaugural season, a total of 19 races were held. After 35 races of the 1969 season, the renaming succeeded in " Grand American ". After the 1970 1971 season, many smaller events were deleted from the calendar and are merged with those of several races Grand National Series.
In 1972, NASCAR changed its structures. Winston was the title sponsor of the Grand National Series, which was called from this point on " Winston Cup". All routes of the Grand National Series with a length of less than half a mile and all races with a race distance of less than 250 miles in a new series, the Grand National East Division were associated with it summarized. In this car the Grand American, the Grand National and models of vintage 1969 were allowed to compete. This series ran for only two years, in the last season in 1972, only four races were held.

In 1971 there was a rethinking of the U.S. automakers, which then invested less money in the race series and thus also in the NASCAR. This meant that the number of participants of individual races in the Grand National Series, in which there was to win less prize money, greatly shrunk. NASCAR allowed the car then also Grand American Series in selected races of the Grand National Series participate. The Grand American riders Tiny Lund and Bobby Allison managed to win races in the Grand National Series. These victories are not counted in the total number of their NASCAR victories, which is correspondingly controversial. Thus was established by the NASCAR that victory with a car from the Grand American Series is the appropriate drivers and cars not attributed, and no points will be awarded for this. In contrast, the victories for the manufacturer counted, as well as the number of racing participation for the drivers.
The series was dominated by Tiny Lund. Lund won 41 of the 109 races held in the series. He also won three of the four championships. The other championship won by Ken Rush, the twelve of the 26 races of the 1969 season, won.
