This F.A.S.T. class Duster, owned by Jeff Patterson of Oberland, Ohio, regularly runs in the mid-to-high-11s at 116 mph. If that wasn't enough to get noticed, he drives the 150-mile round trip to the track! Just your average stock 340 with exhaust manifolds. yeah, right. We don't really know how big the LA is under Jeff's hood, but he would cop to somewhere north of 340 inches. He says the Duster causes quite a stir at his local drags.
