Not quite Delta winged, but this seems to be an inspiration:

Dave MacDonald in Mickey Thompson's Sears-Allstate Special in the middle of the 5th row (14th) for the 1964 500 mile Memorial Day classic at Indianapolis Motor Speedway.

And after that race, and the loss of Dave MacDonald, Gasoline Alley lost its gasoline.
