If it has 350HP, with a chip and exhaust there are going to be some serious deisal trucks there pushing 450HP easily with 700flb of TQ

 

I just tried to equip and price one of the 2007 mega cab 2500 on dodge's web site but it olny will allow a 2006 at this time. Does anyone know if the 6.7 is deffinatly available in 2007 and when can we order one?

 

they will start showing up on the website sometime in early 07. if you go to the right dealer you can actualy special order one right now, however there is no shipping date set yet.

 

I just bought the 5.9 liter, because I wanted an engine that has been tried, tested and proven true. It has been perfected to its current state, and I hesitate to buy an new form. Just my opinion. I made that mistake already with the purchase of the new 2003 Ford 6.0 liter diesel. I think I'll keep my 5.9 liter Cummins, and watch to see what will need re-engineered on this new Cummins over the years.

I realy dont think there will be as many problems with this engine as opposed to the Ford and Chevy. the 6.7L is a direct carry over from the AG market that Cummins has been in for a long time. even though it carries over alot of parts from the 5.9L and it is a different engine, I'm pretty certian this will not turn into the 6.oh-noes

 

i dont think just bumping up the displacement will hurt anything at all.. since its a carry over from the 5.9.... all that really is being modded is bigger injectors, bigger displacement, and a slightly modified head... maybe the cam and bore and stroke may take the upgrade as well, if cummins knows what their doing... then that engine should be a true beast... they havent screwed up before.. no reason to start now

 

saying they havent screwed up before is a tall order, they have had their share of oddities with certian engine lines, when the big cam 400 came out that bad boy would slobber oil like a hound dog munchin down a steak. the head gasket was fine, head torqued down properly, everything good and tight, but there was so much torque on everything you could easily have a gallon of oil drip off the thing overnight from a good days run.

 

hah o well.. that was in the older days to begin with, but at my vo-tech... 3 of our trucks in my diesl shop have cummins in them..... they run really decent for the abuse some of the little bastards give them.. guys ripping off the valve covers and pouring kitty litter into the heads// some kid pissed in an engine... no lie..... i go to school with some pretty sick rednecks..... so yea.. i guess i can say cummins hasnt really screwed up... and these engines are from the 70's mind u

 

my military truck is a M936A2 Wrecker, it has the Cummins ISC 6CTAA and I put that thing through hell, even turned the pump up a bit

 

You should try the new ISX signature 600. 600 horse, 2200 ftlbs, Holy ****.
Is it like OTR trucks in that every truck built after jan 1, 2007 gets these new engines?
