The 1957-19 was a Grand National (now Sprint Cup) - Pacific Coast Late Model Series (now Camping World West Series) combination event held at Eureka Speedway on May 30, 1957. Eventual PCLMS season champ Lloyd Dane had already put a six-lap margin on second place George Seeger when Seeger's crash ended the event early. Dane was awarded the victory, the final of his GN-PCLMS combination race career. Eventual GN season champion Buck Baker did not compete in the event.
