Honestly, I don't think you read a single word I wrote.
1. I said nothing about GM taking the LS3 drivetrain out of a Camaro LS3.
2. LS3, L76, and L98s use the same heads. It's right there in my post. However, I feel you missed that.
3. The LS3 block is virturally identical to the L76 & L98 blocks (which I didn't mention)
Camaro will be much heavier than the Corvette. Therfore, DOD is a given, at least by the 2nd year. The engine will be under greater strain than it would in a Corvette due to the weight difference, so it's likely that there will be some changes. I speculated solid valves instead of the hollow ones in the Corvette.
The LS3 in the Camaro will be very close to identical to the LS3 in the upcoming GXP which will be out a few months before Camaro is.

I KNOW the LS3, L76 and L98 use the same head castings, but the heads are still different on the LS3 (valvetrain).
i never said they would take the LS3 drivetrain away, but if they take away the valvetrain, take away the cam, add DoD, then its not really an LS3 anymore.

It is hard to say what GM will call the motor based on minute differences across platforms. But in general I think big changes result in different designations. For instance, I would imagine if the Camaro got a motor based on the LS3 but with AFM it would not be called LS3. I don't know if it would still be an LS3 without hollow valves, but it wouldn't quite be an L92. But if you took an LS3 and took out the hollow valves and offset rockers it starts to look a lot like an L92 minus VVT w/ car cam (that is unless it gets VVT and then it is an L92 with a car cam). What is somewhat interesting is that all the truck GenIVs have VVT unless it is in a performance truck with a "Corvette" motor (LS2 and LS3 lack VVT). So... I agree that if we start changing around all the features that distinguish the motor's they aren't really the same but who knows what the nomenclature will be.
As far as the motor's go (and afaik) the heads on the L76 and L98 are the same since an L98 is just an L76 without AFM parts, but they are not the same as the LS3 and L92 heads because we are talking about bore differences of 3.988 vs 4.06... all are LS7 based with variation for different bore. The LS3 obviously has a different bore than the L76 and L98, which are both even different than the LS2. They are all GenIV blocks but it depends on what the definition of virtually identical is.

But the 5.0L Fox Cobra R in '93 and the SN95's in '94-95 were no match.

I'm just curious why MauriSSio and friend Trickstang have such an interest in the L76 in the Camaro and the LS3 as a more expensive option.
Most performance oriented people would be thrilled to see more info to support a more powerful engine being making it's way into a more affordable car.

Maybe there is thinking about getting the G8 over the Camaro. Which will not be much difference in performance if the Camaro base V8 is an L76. G8 GT owners will fear the Camaro if it comes with an LS3 as a base model.

Nothing's final till the final tunings done, but that V6 makes pretty impressive numbers in a Cadillac. 
You can speculate till you're blue in the face, but if you're expecting an L76 that's no longer being sold in the cars Holden makes for their home market I have a bridge to sell you.
If you think there isn't going to be a much higher horsepower "super" Camaro some time after Camaro's introduction, then you'd probally buy that bridge.
Ain't gonna happen.
If you are employed by GM and working on powertrains, or getting information directly from them or people close to the project, you aren't going to jepordize your job or you contacts by revealing them. Also, you aren't going to find links proclaiming what any car nearly a year away from sale is going to put out powerwise. Especially in a highly competitive and relatively small segment as sports coupes.
You are free to call BS on anything you want. However, be prepared in this case to eat a bit of crow.
I never understood these types of posts. Very broad negative generalizations that have nothing to back it up, isn't realistic, or just plain silly.
* What car company polls people on engines they have already chosen?
* What "other" car companies actually tell the consumer what they are going to do??
* What facts or credible evidence exists to create the scenario of a 400 horse Camaro getting "waxed" by "that" GT?
Then even after saying that said car company doesn't poll consumers, or let the public know what they are doing, the post is wrapped up with "don't SING it, BRING it", completely opposite of what's just been written.
Just confused by these types of posts, that's all.

I don't think he read mine either.....
My point AGAIN is that...
#1 We will not see the LS2 or the LS7, and those are the ONLY powerplants that GM has openly CONFIRMED will not be in the Camaro.
#2 GM has not CONFIRMED there will be a TOP DAWG with 500+HP
NOW......that aside, I actually agree with basically everything you said
....... Yes, I think LS3 will be an option, it makes the most sense and I cannot see how it wouldnt be. Yes, I think there will be a TOP DAWG with 500+HP.......You may work for for GM.....if you do, GREAT!!!!!!! Love the work you guys do. You also may also have access to inside information and know something the general public doesn't........ GREAT!!!!!! I want you job!!!! There are plenty of the guys on the forums that are involved in the Camaro project.....and we all know who most of them are, and we are VERY thankful for the snippets of information they give us from time to time .....
There are also plenty of smarta$$e$ out there who think they know everything about this car.....they may sound like they know alot, but they have ZERO crediblity.......Soooooo, if you are gonna come out and annouce to the Camaro world that......."LS3 WILL BE IN THE CAMARO" or "L76 WILL NOT BE IN THE CAMARO" or any other bold statement that we don't already know for FACT...... THEN HAVE THE SH*T TO BACK IT BACK UP.......
If you can't.......then you have no business making such as statement and your credibility is just as good as anyone else on the site. Your comments are simply you welcomed thoughts, opnions, and ideas that I truely enjoy reading, we all do or we wouldn't be here .......but they are not fact.......not yet.........

Careful fellas, there's a lot of good "advance insider information" here, but can't always be backed up. If it all could, it would be "general public information". Be selective about what you believe and all, but don't assume it is all junk when it cannot be backed up.

truth is, i think we're all just trying to get to the FACTS. Everybody is just assuming that it will have an LS3 as a base V8 and be sold for $25K, im just playin the devils advocate and presenting the other possible scenario, which actually makes more business sense.

If your truly trying to get the facts then understand that many of the facts are not available yet. But there are are plenty of hints and rumors popping up. Nobody is going to put some GM employee or supplier contact that is giving us info about the car on the internet. This info we get in these threads is like insider trading and you can choose to do what you please with it.
You also keep saying that your scenario makes more business sence. Well I certainly don't agree with it and If I know GM like I should then I don't see your scenario playing out. I think your scenario makes a poorer business case. 2 V8's that do not cost any more to build with near the same hp is added costs in: development, design, manufacturing and also tends to lower quality ratings as there are now more variables to deal with. GM needs to cut costs on the Camaro not raise them so they can have a specific model to "fight" the Mustang and Challenger's hp figures.
