Hello; They ought to be careful drag racing with that kind of commodity. Gold would be the safer option with lumber prices these days! Old whitey is a power making beast. Would love to see these guys coming rolling through our town. I'm sure all those bleeding hearts would have their britches in a tight wad. I have so many questions. When they're dropping the pedal and the cabs tilt to one side, is that from all the torque trying to spin the drive shaft under such heavy load? Are they running with turbos or even super chargers? Not even sure if you could put that on diesel. It's now on my list to see one of these events live.
