I was just thinking about how the 2008 C6s are supposed to get the
LS3 and what if they were delayed until mid cycle for the 2008 models? How bad would that suck! I'm waiting to order/trade for an 08' C6 when they become available. But do you guys think there is a chance GM may not drop the LS3 in until mid production cycle or do you think we will get it on the first 2008 models?

I sure hope they don't pull some delay crap. Can you imagine how many pissed off early 08' buyers there would be if they got an LS2 only to see the LS3 out a few months later? What are the odds of this happening?

 

Probably very low odd's on it happening ... the switch to the LS3 is a cost saving measure, and GM want's that to start ASAP.

With the LS2 phased out, most, if not all, LS? engines are now on the same block casting, different materials, but same block. Which save's GM a ton of money.

Look for GM, and other OEM's to start doing this more and more often ...

 

No worries.

 

Do you know something I don't?

 

, I know you have nothing to worry about

 

I'm waiting for the C7.

 

C11 is right around the corner

 

Do you have some reason to believe they would be?

 

Well, why don't you just wait awhile to know for sure. And, then buy/order your car?

 

With all due respect, I don't see what all the excitement is about the LS3 engine. The small, anticipated increase in horsepower could be easily achieved and exceeded with simple modifications to the LS2 engine and will likely not even provide a SOTP feel.

The LS3 engine will purportedly be a Displacement-on-Demand (DOD) engine where to maximize 'efficiency' the engine will run-on only 4 cylinders under certain circumstances.

DOD is a radical departure for Corvette and a strange departure for a performance car. IMO the DOD engine is not being implemented for the purpose of enhancing performance but rather as a 'concession' to Governmental CAFE requirements and for other reasons. I do not purchase a high performance car with concerns about fuel efficiency and mileage. I want performance as the determining criteria for a major engine design change in the Corvette.

IMO General Motors is polluting the Corvette with the DOD engine. GM has lost their focus on performance. Make no mistake, the new LS3 engine is not about higher horsepower or increased performance….it is about appeasing Governmental regulations and GM’s own cost-cutting measures.

I believe the DOD engine is better-suited for Grandma's Impala....not a Corvette!

 

GM has lost their focus on performance?

The speculation of DoD on the C6 originated on the internet. That doesn't mean that it's going to happen. Apparently GM offers at least two 6.2L engines that do not have DoD. It is possible that the LS3 won't have it.

Nobody for a minute is saying that DoD enhances performance. If GM does include DoD on the C6, it's because they have to to avoid guzzler tax.

I'll use an extreme example to illustrate my point:

If you had a choice of a 400 HP engine without DoD or a 450HP engine with DoD (because they both just barely escape the guzzler tax), which one would you choose?

Personally, I'd be willing to live with DoD for a 25 HP bump. And if it bothered me, I'd get it turned off by a tuner.

 

 

The original post in this thread is exactly how rumors get started. With absolutely ZERO official information available, we've got:

1. The 2008s will have the LS3 with DOD.
2. The 2008s will have the LS3 but not with DOD.
3. The 2008s will have the LS3 but not at the beginning of the model year.

What possible reason would you have for suggesting # 3?

 

I have a 2005 Dodge Magnum that has their 345 HP hemi in it. It also drops 4 cyl at highway speed. I can say that I have never noticed when it does so. If I stomp on the throttle there is no delay in it's accelleration. So don't fear this technology assuming the General can do it as well as Dodge has.

 

I just herd a few comments by a couple users a while back about mid production cycle possibility. Just rumors, but the thought scared me.

Please lets not make this another DoD thread!

 

This thread and the thread "Uh-OH, wrong heads for 2007" should be merged and purged. The sky is falling, the sky is falling!
You guys are worried about the LS2? The LS2 is a damn good platform. Now, if we were talking Vega...

 

thats why i don't understand why they are going to stop making it only after TWO years of production.... . i personally think there is not going to be no LS3 until the C7 comes out. but thats just my opinion

 

so has the speculation, that there WILL be an LS3 for 08...

 

They've already run the '08 validation cars down the line in Feb, and they had LS3's.

 

Yep, you wait. The resale price on the '05, '06, and '07 C6's will start to go up JUST BECAUSE there is NO DOD.

Don't hope for it when they make your car - hope they put in an LS2.

Can you imagine the complaints next year: "my damn car ran on 4 cylinders for 3 weeks before they figured out the problem" and on and on and on - no thanks!
