Brian Lent; If you want a truck with just a tune then the 6.4 looks good. If you want 800 hp then get a cummins. Most guys that buy these things don't haul anything but parts for their trucks. .[/QUOTE said:
IMO, this new motor is just as capable as the cummins in either hp. class as you have stated, cosidering the 6.4 makes 800 just as easy or easier than the cummins from what ive been reading and just tunes alone is over 500 hp.
If i had a choice, to run any diesel motor combination, it would be a toss up for sure.
