I had to have my old 95 Cummins powered dodge flat bedded one time, just for a blown fuel shut down solenoid fuse. The flat bed had a Duramax and I was impressed with the way it pulled itself with my truck on it's back, and my truck was a heavy 2500 with utility body.
That was compared to the 160HP the 95 had, my 07/Cummins 6.7L has 300+ HP now.
Not considering any other factors, the Cummins does sound the sweetest!
Not to stir up a brand war but I was at Harbor Freight the other day and a guy had just started his Ford as I was getting out of my truck, the thing sounded terrible, like when you cold start an old diesel engine in sub zero temps, but it was not that cold. he was letting it run and revving it a little trying to get it come back to normal but it wasn't. Not sure of the year but it was a late model diesel.
I felt bad for the guy, I know that's not indicative of all Fords, that truck was really having a problem, but I thought for a moment about those funny Howie Long GM commercials where he's patting guys on the back, wishing them good luck with there non GM trucks. This poor guy probably would have punched him!
