Has anyone read anything about what the 2013 HD DMax may have? Will it still use the LML?

I know the body will be different but Im just curious if I should throw more money in my truck or leave it as is and wait for the 2013 next year

2014 will be the next generation....

Light duty.

Thread moved to new vehicle information forum.

I heard late 2013 for the next generation K2XX light duty, no idea on the HD's yet, probably at least a year later. Don't know how accurate this is, but I have been told the next generation HD's will use the new 2011 HD chassis and suspension. So don't hold your breath waiting for a return to SFA and leaf springs!

Kinda just curious if HP ratings will get bumped from 400/765 to say 430/800
If that was the case Id be all over one. Wanting that extra power without having to add any mods

Explain.

No idea. I don't think they will try to get much more out of the current 6.6L Duramax, but maybe the next generation? We also might be seeing the 'high water mark' of diesel power right now, tighter emission standards could slow the horsepower/torque race down.

Gas engines might be a different story. There has been speculation that GM has a 7L gas V-8 under development. No idea just what that might be, a Gen. 5 LS or ??? There have been rumors that a more powerful gas engine might be an option soon, before the next generation HD's come out.

wheres the info on this 7L?

None yet. Like I said, just a rumor at this point. 'pickuptrucks.com' reported on it, and they think it will be direct injection. Some figure 400+ h.p.. My question is will it be based on the LS or is it some new generation Big Block.

wouldnt they be better off using a ls7 engine in the trucks for there big power gas engine.

I am betting that the next gen Dmax will still be a better option for pulling and for mileage compared to a 7L gasser

Yes and no. If you don't tow that often or that heavy, you are cheaper with the gas. It takes a lot of miles to recoup The added price tag of the diesel. Also there's people out there that only see gas is cheaper fuel and the convenience of a gasser.

LS7 has a dry sump oil pump and various other items (titanium valves, hand built, forged main caps, etc.) that make it not necessarily the best engine for a truck. My opinion for a new gasser is direct inject one of the smaller motors 6.2L for example and you could easily have a 430+ HP 450+ lbs.ft motor that would get better fuel economy than current motors (if they refine the cylinder deactivation technology to where it works a little more often.) Personally while I like all of the power of the current D-max I would rather keep the power around 800 lbsft and get a 7 or 8 speed tranny with a super high od gear in it to maximize unloaded driving that could be locked out at the push of a button.

I think if they took the current Gen IV engines, made them 3 valves/cylinder, and added direct injection (SIDI), that would make a really nice setup that would still be just as reliable and almost as simple/inexpensive as the current Gen III/IV small block V8's. And it would make more power, and be more efficent.

If the gasser can have 450/450 or close to it and get 14/20mpg or more I may think about it.

Probably no need to go with a 3 valve head. Ford got quite an improvement going to a 3 valve head on the Triton V-8's and V-10 only because the bore on a Triton is so small that the cylnder walls shroud large intake valves, so 2 small intake valves offered better breathing. The LS does not have this problem. Notice the Ford's new 6.2L V-8 went back to a 2 valve head. The 6.2L has a large bore and can handle a good sized single intake valve, just like an LS can.

I believe the previous post about why the current 7L is not used in trucks is right on the money. The LS7 is a very expensive engine and not well suited for high torque truck use. In addition, there would probably be durability issues with the alloy block and thin cylinder walls in heavy duty applications.

sorry but ''BIG BLOCK CHEVYS'' are DEAD AND GONE FOREVER
