During the preceding season, NASCAR had completely stopped tracking the year model of all the vehicles and most teams did not take stock cars to the track under their own power anymore. Only manual transmission vehicles were allowed to participate in this race; a policy that NASCAR has retained to the present day.
The NASCAR Winston Cup Series was also plagued with top teams running big engines and finishing in third place to avoid inspection around the time that this race was held.
