The 1986 Miller High Life 400 was the second stock car race of the 1986 NASCAR Winston Cup Series and the 32nd iteration of the event.

[1] In what is considered to be one of the most controversial finishes in NASCAR history, Junior Johnson & Associates' Darrell Waltrip and Richard Childress Racing's Dale Earnhardt engaged in a battle for the victory.

In the third turn, Earnhardt spun out Waltrip, sending the two into a crash that included numerous other cars behind them.

As a result, the next driver behind the two who managed to avoid the wreck, Wood Brothers Racing's Kyle Petty, was declared the winner in improbable fashion.

To fill out the top three, King Racing's Joe Ruttman and the aforementioned Earnhardt finished second and third, respectively.
