6.7L Cummins, good bye old faithful!

I know this is a PSD forum, thats why this is in the general area. In the recent Diesel Power mag, there is a short bit on the replacement of the good old 5.9L Cummins thats been in service for ever. It is a 6.7L inline six that makes the same HP and TQ as the old engine. Its to meet new emissions(you know bigger engine less overall power) and the new fuel reulations coming down in the near future. It is supposed to be out starting with '07 trucks. Included with the engine is a new tranny and possibly a long bed version of the new mega cab truck. Can you imagine the size?

I don't think that dodge will do an actual 8 foot bed simply for the reason that it would just be too daggone long. I do think that they will have a model with a longer bed that can better accomodate some of the larger 5th wheel trailers that the current megacab can't without risking trailer-cab contact. Something like a 7 foot bed might do the deed. I love a long bed and a huge cab though, so if they had a mega cab with a 8 foot bed and I could afford it i'd probably buy it! As for the engine I'm sure they'll waste no time pulling extra ponies from it. Amazing, I've lugged my engine in way low gears trying to get it to smoke and it won't do it......and they're still gettin crap from the government on emissions!

Well I've read a few things on having a longer bed with the mega cab, its actually only 12 inches longer than fords crew cab. And exactly what you said, the 5th wheel thing is the problem. That motor is already said to be at like 610 ft. lbs. and 300 or 325 hp, whatever the current 5.9 is I don't have the article in front of me.

You would think that with more displacement that emissions would go up.....I don't know, I don't understand how it all works but I trust Cummins will not let cummins fans down with a somewhat problem plauged engine like ford did switching to the 6.0......and jeez......12 inches longer.....wow I thought it was a pain to park my cc/lb 250 when I had it!
