I ran across this article while searching some open-wheel racing history. It's dated 1996, around the time that Mopar decided to get back into short track open wheel racing in the US big time. I'm better informed about WOO than I am about Silver Crown, but I believe that Silver Crown was (is?) the biggest motored sprint car series that did not have wings. http://www.theautochannel.com/news/date/19960701/news01115.html More on Sills and the Silver Crown series. This is from Mopar's own "Milstones" site. Shows how you can market "Performance" when you support US racing series.
