i own an '04.5 3500 SRW cummins powered 4x4, as well as an '05 3500 DRW cummins powered 4x4. both can be seen at
formatting link
the '04.5 has the cummins 325/600 and the '05 has the 325/610. both are automatic and both have 3.73 gears. the '04.5 is however, noticeably more powerful than the '05. the '05 isnt weak by any means, but the '04.5 runs circles around it and i dont believe the weight of two extra tires makes that much of a difference.
at this point im trying to figure out of i got lucky and got a powerful '04.5, or if im unlucky and got a "weak" '05. any ideas why there would be a noticable difference? thanks,
