Driver Nate Vegh (right) and Will Hardesty, builder of the truck, have
known each other since Nate was a young boy—back when Will used
to turn wrenches on his father’s ’99 F-350 puller. When the trio reunited
for the Jumping Jack Flash project in 2016, the truck pulling world was
far different than it was back then. So far, these guys have relished the
opportunity to campaign a Pro Stock 7.3L in one of diesel motorsport’s
most elite, Cummins-dominated pulling classes.Put together by Ferenc X Vegh Jr., his son Nathan Vegh, and Will Hardesty, the Jumping Jack Flash Ford is one of the
freshest faces on today’s Pro Stock diesel truck scene. In addition to being lifelong Ford fans, Ferenc, Nate, and Will
were partially inspired by the “Trailblazer” Massey Ferguson campaigned by Dan and Travis Kuhns—a V-8 Pro Stock
tractor that holds its own against the nastiest John Deeres in existence. If you’re fortunate enough to catch Jumping
Jack Flash on a long track, it can top out at 33 mph while carrying as much as 5,400 rpm.52 OCTOBER I 2019 • DIESEL WORLD http://www.dieselworldmag.com
