im not taking sides at all, but it seems like every time either of you offer to run eachother...neither of you show up, then bring a ton of excuses. i wanna see what happens when these two guys run. Obviously rob is gonna spank him in the quarter, Mike has a stick and looses boost on every shift. DUHR! next tarded point, Rob is gonna outpull him because he has a super long wheel base, and an auto tranny (once more). The 6.0 is not a better engine than the Cummins. the Torque shift is not a better tranny than the NV4500 or NV5600. that cummins will hold tons of power till the cows come home, and the NV4500 needs a good clutch and will do the same. When those 6.0s get high into the HP they are gonna need bottom end work, and after half the number of mods the cummins gets(hp wise) the Torque shift needs some components. With that said the aftermarket for the cummins is damn near infinite. The 6.0s market is just emerging what with Bean making injectors and turbos as fast as he can get cores, and ATS spending countless hours in the R&D room...
Its not really a whos is bigger match, its whos truck has certain qualitys.
Just my .02
