Ray, I read also about the Dodge breaking the land speed record with the Cummins Dodge. I don't remember how fast it went, but it also was a Gale Banks modified diesel. It seems they towed a trailer with speed equipment with the truck they ran. After the run put the speed equipment back in the trailer and drove the truck back home. It is amazing what Gale Banks can do with a diesel, but his stuff is very expensive. I just leave mine stock.
