The International Super Modified Association was founded in 1974 by multi-time Oswego Speedway champions Jim Shampine and Nolan Swift to ensure the future and longevity of supermodified racing. With the help of a Central New York businessman, Tom Heveron, Shampine and Swift formed ISMA as a forum for owners and drivers to express their ideas and opinions.
