ISCARS Dash Touring Series
The ISCARS Dash Touring Series (previously known as the NASCAR Baby Grand National, Goody's Dash Series and IPOWER Dash Series among others) was a stock car racing series created by NASCAR in 1973, running solely at North Wilkesboro Speedway, that involved V-6 powered cars raced over relatively short distances. In 1975 the series branched out to other tracks besides North Wilkesboro Speedway. After the end of the 2003 season, NASCAR transferred the Goody's Dash series to IPOWER (International Participants Of Winning Edge Racing). In 2004, they ran the IPOWER Dash Series. In January 2005, officials announced the cancellation of the 2005 Dash season due to problems with sponsorship. The International Sport Compact Auto Racing Series (ISCARS) purchased the series allowing the series to continue through 2005 and was operating until 2011.
