I have to admit that I didn't know this about WoO sprint car racing.
The longest WoO race was held at Paragon Speedway, Indiana in 1978 - a 150 lapper.
The winner was - Steve Kinser
Info source: World of Outlaws Yearbook - 1986, pgs. 59 & 64.
Have a good day...see you at the races
Rich - Arnold, Missouri
NOTE: If any IOW reader was at Paragon Speedway for that WoO race in 1978, I would surely like to get your input on it - thanks.
