Nice video well done. What were the mods? did I see a different Tb ? what else?
Looks like the intake, a BBK TB, headers, some serious rear suspension work, notice the plexi-glass cover over the front. They obviously put this thing on a serious diet and it's got some low gears. Great times, pretty consistent 11.80's with a couple bad runs low 12's. The guy for the most part has crappy hole shots but he can shift most of the time.
Truck had a tag so street legal ? It was an 04-05 version but I'm not 100% sure because they modified the front clip quite a bit.
No telling what the engine internals look like but probably heads and a cam minimum. Awesome!
