cool vids,and cool truck. but i'm of the mind set that wheel speed is very important for bogging. i'd rather have smaller tires and a healthy big block. but thats just me, i like power. I respsct your opinion fasel, but i like the dana 60/14 combo because it's much more practical. i like practicality lol. that guy is obviously not driving his rig to the mud bog. my dream truck would probably be his truck, but sas'd on 38's to 40's, with major work done to that 6.0. it's a great engine with not so great mileage. but i love fuel injected chevy engines. just my opinion thogh.
