***This video was taken while the truck was still under construction***440 with 671 blower, dynoed 680 horse@ 6600 RPM. We decided to test out my transmission , the first run I think I accidently bumped it to neutral, second run was clean all the way through 3rd gear. Good thing I dont plan to shift in the mud anyway, its just nice to know things are working properly! I need to upgrade to 70 shafts in the front before I lock it! Heres a couple links to the videos of this in the mud:    • Blown mud truck test run, mud boggin   and    • Blown mudtruck, mud truck
