Jim Shampine ran many many many years and always seemed to have the number 8 in a pool ball for his car numbers...he ran sprints, supermodifieds and I'm pretty sure I have even seen pics of him in a stockcar and Nascar style modifieds, all with that same 8ball for a number. Most of his cars were baby blue, but I think I have seen white and or black on his cars also...I am not saying you are wrong about the last name you mentioned because I know there have been plenty of guys use 8ball for a number throughout the years, but Jim Shampine was synonymous with that number/graphic for 20-30 years...I think he was from further east (New York or somewhere) but he did venture that far west to race more than a few times.
