History
The 1963 and 1964 IMCA champion, Dick Hutcherson, was not eligible for the 1965 NASCAR Grand National Series Rookie of the Year, which he won nine times and finished second in the standings; it was given to Sam McQuagg. NASCAR's rookie standards have since changed to being based only on the NASCAR Cup Series.In 1979, IMCA held its first IMCA Modified race at the Benton County, Iowa Speedway.
