As an owner of a Pantera automobile, Roger Butzen entered his car into the Pantera International Winter Expo in 2007. As the proud builder of his highly modified Challenger V8, Roger carried it along to please the onlookers and, to their surprise, he fired it up to a roar. As predicted, his Pantera did not receive any awards; however, Roger walked away from the expo with the “Best Engine” trophy for his Challenger V8. The trophy is on loan to the Miniature Engineering Craftsmanship Museum courtesy of the Engine Collection of Paul and Paula Knapp.
