Prior to 1955, Flynn would compete exclusively at the Daytona Beach Road Course for the "Modified" and "Sportsman" divisions of NASCAR.[2] He would drive Ford vehicles from the late 1930s during his formative years in professional stock car racing.[2] As a competitor in the 1955 Southern 500, he had the fastest finishing Ford in the race with a fifth-place finish.[3] Flynn's impressive accomplishment gave credibility to the Ford racing teams that were racing in NASCAR during that era.[3] During the 1956 Southern 500, he would crash into fellow NASCAR driver Bill Brown in an incident that would cause the fence to be temporarily broken.[4]
Flynn's total career earnings in the NASCAR Grand National Series were considered to be $1,700 ($18,315.7 when adjusted for inflation) and he finished 1162 laps (1439.6 miles) of racing.[1] Flynn also racked up a single top-five finish in addition to his only top-ten finish.[1] After suffering from complications due to his diabetes, Flynn would die in 2007 at the age of 77.[5] Most of the races in Larry's NASCAR Cup Series career were done as a driver/owner.[2] However, he would race in the 1955 Southern 500 under the employment of Mr. W.R. Waldon.[2][3]
In 1970, Flynn won the Bobby McKim Memorial Race at the 0.375-mile (0.604km) DeLand Drive-In Raceway, having set the fastest qualifying time for the event.[6] His ultimate retirement from motorsports came from a 68th-place finish at an International Supermodified Association (ISMA) race at Daytona International Speedway on February 1, 1976.[2]
In 1955, Flynn finished second at Langhorne which was a major Modified-Sportsman race.[citation needed]
