I'm sticking with super street. So that requires 6000 lbs and no fancy transmission. 4R100 has a long way to go on proving grounds before I think about that. To my knowledge nothing real big in HP has ran one. Skinner has in his pro street truck but chased other issues so hasn't got a lot of time on it I don't believe.
Not sure if you meant Newtown, VA (The one closest to the coast. There are two of them on MapQuest!!!!!!) or not. They also have a top notch sand facility and race every weekend.
Yup they have a monthly diesel list race. And one big diesel event a year.
