The 2004 Winn-Dixie 250 was a NASCAR Busch Series race held at Daytona International Speedway in July 2004. It was won by Mike Wallace after a wild finish. Jason Leffler and Michael Waltrip crashed on the last lap, and Leffler, trying to maintain the lead, blocked Dale Earnhardt Jr., allowing Wallace to blow by. It was Wallace's first win since 1994 and the first for Biagi Bros. Racing.
