IMCA Stock Car Series History

The International Motor Contest Association (IMCA) was organized in 1915 by J. Alex Sloan, and is currently the oldest active auto racing sanctioning body in the United States. Sloan, a native of Pittsburgh, Pennsylvania, was instrumental in establishing the IMCA and ran more races than all other promoters in the United States combined, all under IMCA sanction. After Sloan's death in 1937 his son, John Sloan, continued to manage the IMCA. Under John Sloan’s leadership, IMCA continued to grow and held its first Late model race on November 9, 1947, in Lubbock, Texas. This group is dedicated to the Stock Car division of IMCA and the drivers who raced in it throughout it's history.
