In 1978 the three year old National Hemi Owners Association had become so successful at developing, fulfilling and promoting Chrysler enthusiast parts, information and activities that non Hemi owners were openly encouraged to join and enjoy the benefits too. The new group spun off was named Mopar Muscle and its logo was the Plymouth “heart” of the late 60’s. The heart was symbolic of the spirit of the Chrysler enthusiast. Roland Osborne, founder, appointed Jim Tamm of American Racing Wheels and Dennis Huff as original directors. A short time later, Christina Grinius offered her gifts to the organization and during her watch until 1986 Mopar Muscle far surpassed all the other Mopar oriented clubs with many of the local and regional clubs and events very much still viable today.
