ROSSBURG, OH (April 10) – Eldora Speedway officials have announced an update to the participating divisions in the April 27 Saturday Night Speedfest on the historic .500-clay oval. Joining the UMP DIRTcar Modifieds and Eldora Stock Cars will be the Waynesfield Raceway Park Truck class that had a successful run during last fall’s Blue Collar Bash. The trucks will replace the previously announced Front Wheel Drive (FWD) Compact division.
