Those things are scary. A friend of my dads used to have one with a fairly hot 360 in it. The thing ran 12. 7s at around 105mph. He took me for a ride in it on the highway one day. Going over 100mph in one of those just does not feel right lol. As I am watching the cars fly by I look over and see how much slack he is fighting in the huge semi like steering wheel and well... i was kinda scared lol.
If you want to know what a cummins would sound like in one of those start your truck. Lay down on top of the motor and shut the hood. Then have someone get a HUGE fan and point it at you. That way you have all the diesel and wind noise you can stand. And that would be almost lifelike lol.
