Not my truck,but a truck i built a DTT trans for,he has a redline box. He was at the Fall brawl, Trevor Wood. His truck runs like a scalded dog with the Redline box. He picked up 10hp over a TST powermax competition box as well. He dynoed the TST with an edge ez,unhooked the TST and hooked up the redline,(kept the EZ)and rolled again all within 10 minutes of time. The truck runs great,and pulls incredibly hard . The truck burys the tach with ease. I know he has the Mitchel valvetrain on his truck,and a B1/B2 twin setup built by Nate Wright as well.
