As for a stock tranny going 11s, I loved that truck but don't count it. It was a Dmax transplant into a stripped short bed. If Orange Crush went 11s on stock trans it'd be no different. I think the fastest ever on a stock trans is a 12.78.
Not to argue, but wasn't it a just an 06 LBZ backhafed and four linked?
