Over the years the United States Auto Club has occasionally run "Special Event" races which were sanctioned for a series, but did not award championship points or co-sanctioned a race with a different sanctioning body or other USAC series, again not awarding points for their own/one of their series. The Third Turn has compiled what results we have been able to find for these events here. If you have any information we're missing here, or results that we have yet to include, please contact us.
Note that this list is for USAC-sanctioned Sprint Car events. For USAC-sanctioned Midget Car events, click here.
