That 1000 lbs has to go somewhere. Lighter engine? Lighter frame? Weaker sheet metal? Check this link where someone loaded a RZR utility vehicle in a Chevy and dented both wheel wells.

 

Not true. The Dmax is on version 5 I believe.. They have monkied with injection, pistons and rod designs as well as block improvements since the release of the LB7. They have ALL stretched to make emissions, Cummins is the only one that is 2010 compliant NOW... FWIW.

 

Not to mention the 6.7 shares 30-40% of the 5.9s parts.

 

What's not true? What KMKDiesel said is correct.

 

So it shares some parts, Cummins even calls it a new engine.

 

My brother in law has a 2005 D-Max 3500 DRW 5 spd Allison with all the bells & whistles. It is a nice truck inside and out. Rides nice and performs pretty well, but after driving it I think my truck is considerably faster and I know I get better mileage. Of course his is a 1 ton dully so it weighs at least as much as my 2500. Another thing is that he has overheating problems if he pushes it at all when towing his trailer, which is common from what I hear for the 2005 LBZ engine. I thing that the new LBL engine fixed the overheat problems that they had with the LBZ, but it seems like they have to come out with a new engine about every year, and that can't make it easy for servicing. They will need another new engine by 2010. I will stick to Dodge.

 

i believe 2005's were LB7's (not sure) . only the 2006.5's-2007's were the LBZ's i do know that much.

 

'01-'04=LB7
'04.5-'06=LLY
06.5-07.5=LBZ
07.5-NOW=LMM

This is out of my failing memory but its close. There is a half year difference in the somewhere but, I don't recall off the top of my head.

P.S. I drove all three (ford, GMC, dodge) the other day. I will post my comments sometime. All three are fairly impressive if you don't think about the emission issues.

 

Oops, I think you're right. My brother in law's truck is a LLY. They have so many different engines it gets hard to keep them all straight, which was one of my points.

 

I wouldnt really call them "different". Most parts are interchangeable between the 4. Basically akin to the differences made to the 5.9 over the years. (YES I know the 5.9 stayed in a certain 'generation' for longer periods of time, but remember the 5.9 also existed in a time when (for the most part) emmissions regulations did not exist...so no changes were really necessary.

Its too bad that the 7.3 did not meet the up coming emmissions regulations. Several main things about it...2 valves per cylinder, etc was not going to cut it as far as the EPA was concerned


LB7 --> LLY changes: Different heads, injectors, variable vane turbo, EGR added
LLY --> LBZ changes: different injectors, new ECM, revised turbo and EGR, intake grid heater added, SLIGHTLY bigger rods and revised pistons (ALL short block parts interchange with all other dmax's)
LBZ --> LMM changes: revised EGR, DPF added, intake air throttle body added

you can pretty much build up a custom duramax grabbing parts from every generation. A lot of guys start with LB7 block's, use LLY heads, use LBZ pistons, etc...

 

Right, but it seemed like the perfect opportunity to state the obvious

 

I tested an '08 F-450 Lariat pickup a few weeks ago. Aside from the engine, that truck is a wonderful engineering specimen. The transmission, suspension, interior, brakes, etc are all better than anything you can find on Dodge or GM.

Not very high on the 6.4L, though, and I simply could never buy a GM pickup even though the D-max is a pretty darn good engine.

I wish Ford could offer the Cummins in its pickups.

 

I would think that the Ford would have came up with a tranny similar to the 6 speed Allison or the 68RFE which both have double OD. My old man has an 08 F350 and is somewhat impressed with the truck, but the mileage is not very good. I know it should improve some with more miles, but he is getting less than 14 with it. IT would take a lot of breaking in to get it even close to 20 or even 18. I like Fords, and drove them exclusively before my Dodge, but I can honestly say my Dodge is just as tight and drives very well. Guys are crazy when they tout "how much better a Ford body is". It is crazy. They are all good, it all comes down to what the owner wants to see when he gets into his truck every morning. Scotty

 

You never know. Like every once in a while some of those 1st or 2nd gen guys will come in here lamenting the fact that 3rd gens are now $40K and $50K+ trucks that no-one one can afford anymore. Like ten years from now when they cost $100,000 we'll be like a bunch of old farts talking about the good old days when they were 40 or 50K

 

to be honest, i was waiting for a reply from the bank on financing for my 08 ford that i already signed papers on , and i took it for a test drive.i was NOT impressed at all. I now have 6000 miles on my truck and it has gotten so much more powerful than it was day one. my friend has 20k on his 6.4l and his will take mine in a race. Its a tight motor that needs breakin.

Also you dont feel the 6.4 power through the suspension. its so smooth you have to watch the speedo to see whats going on.

I hated the 6.7l. The dmax was very nice. I like the 6.4l tho
