I think its one of those if you have to ask,things. I have video of the truck blowing the tires off at the 330 mark on low boost somewhere
 
Thats a bad ass truck. Still AWD?? Usually at that level, the AWD set-up just dont hold up anymore. If it is, thats one hell of an accomplishment. I see a transfer case mentioned, so I believe it is
 
i seen the truck personally.... words cant describe it its truly one of the most bad ass turbo era gm cars i have ever seen.... its also one of my dream trucks but god knows i cant possibly shelter this beast.
