Not sure if this counts, but I believe Terre Haute ran a non-sanctioned, non-points match race with Silver Crown cars during the 1996 U.S. Dirt Nationals. The race was only 10 laps.

RESULTS: 1. Jack Hewitt (#63 6R Racing), 2. Tony Elliott (#62 Beaver Racing), 3. Dave Darland (#6 Ralph Potter), 4. Dan Drinan (#43 Ricky Nix). 4:08:21

DID NOT START: Kevin Thomas (#12 Galas)

LAP LEADERS: Laps 1-6 Elliott, laps 7-10 Hewitt.
