L76 camaro ?

I was looking at the new pontiac G8 and noticed that it dose not come with the ls2 or ls3 but with the l76 DOD 6.0 motor rated at 362 hp. I would seem a likly possibility that since GM has only announced 1 v8 I beleave for the initial model camaro; that this may be what we are to be looking at? It would still out perform both the mustang and the challenger base V8 models and would leave the ls3 for a more expensive Z28 model while allowing consumers to get camaro v8 power in the 29,900 G8 price range perhaps instead of 34-35k of a Z28 package.

It may only have 362hp stock but the use of the l76 intake means square port heads and easy L92 head swaps for big power. And the DOD will allow for much improved fuel economy wich could boost sales.

I have no real proof or anything, just sharing thoughts.

there is alot of talking about this here. I'm not assuming anything without more information as we were told to forget what we know about motor options for the camaro

L76 is one of our best guesses for the lowest (possibly only?) V8. It has been discussed at length here . . . mods please merge threads

This is the thread (no pun intended) that we're all hanging onto:

A lot of us hope this means we'll see a Gen V engine(see sticky in engines forum) upon initial release. But nobody here really knows. (sigh) Only those at GM...........

Not quite. They're more directly related to those found on the LS2, and LS6 engines. With rectangular ports like the LS7.

The L76 has shared parts with a lot of other GM engines. I still hope we see a moderately priced engine with AFM, VVT, and DI to replace the L76 that is cost friendly with a lower initial purchase price, lower insurance costs, and better fuel efficiency. The L76 represented all that to me, but I'm sure they'll have a suitable alternative.

I'd have no problem with the L76, as you said, it has the major points; AFM better fuel mileage, plus one you might have forgot, it runs on Regular gas not High octane. But we have to also remember, on one of the threads here someplace there was a message from Scott hinting at a completely different engine in the works for the Camaro (Not his exact words). Found it, look at about four posts below this by Dragoneye.

Is the l76 the same engine used in the full size trucks? Sorry, still learning the GM nomenclature. I know I rented a penske truck with a 6.0 and the engine was a beast in that thing. The truck was a wimp though. I had way more engine than truck.

This may not be a bad choice for the camaro. I can live without 400 plus hp if I have gobs of torque.

The L76 is plenty torquey, but it isn't exactly the same as the truck engine. They are closely related. There is a sticky thread with L76 info, and I think it might explain the difference.

So how many different v8s does GM have for use in cars right now? Is it just 3 (ls3, ls9, l76)?

it is my understanding that with a simple tune and 91-93 octane it is expected to be back up to around 400hp from its 87 octane 362hp tune.

I think the l76 will have more in comon with the camaro production engine than the ls3 has. maybe we will just be that lucky and we will get the gen V motor with all the bells

Right now there are

6.2L LS3 -Base Corvette
7.0L LS7 -Z06
6.2L SC LS9 -ZR-1
6.0L L76 -G8
5.3L LS4 -Impalla SS, Grand Prix GXP,Monte Carlo SS, Buick LaCrosse Super
4.4L SC Northstar
4.6L Northstar

I think thats it.

the l76 does have like 398 ft pounds of torque. that makes a biiiiig difference. most cars do come out with more HP than torque from what i've seen. I can't wait to drive a manual G6.. hell i might end up with one.. but then i'll have a probelm getting a camaro unless i sell or trade up .

Hey, does anybody have a subscription to GM high tech performance magazine?
IF so...I just read something interesting in an LS9 blog on their site:

Quote:
Pick up the April 2008 issue of GMHTP for an in-depth look at this new engine--as well as a sneak-peek at another high-horsepower GM mill coming down the pike!
Sooooooooooooooooooo - would somebody kindly let us know what the deal is in this magical April issue? I don't have a subscription to them, sadly...But I'll be paying attention when April comes!

I think they're talking about the new Gen V engine but I might be mistaken.

That's the first thing that crossed my mind. So far, only Wards has said anything about it, I think. If it makes it into GMhightech.......but I'm not holding my breath on those coming out so soon already - I'm just hoping against hope really, really, hard:
<= me...hoping against hope

Yeah, everyone is making much ado about the end of the Northstar program, but the possibilities of the new corporate Gen V plants are exciting enough to make up for that. I've faced the fact that future demand for V8s will probably be low enough to justify one corporate V8 family, but if that family just kills everything else, you won't see me complaining.

I've never understood why there needs to be more than one or two different v8s anyway. Just use one v8 for the trucks and one for the cars. If you want different horsepower for different models of cars, you can just tune the engines differently. By only having 1 engine that can be used in all cars, you would save a lot on manufacturing costs.

Does anyone know why we need multiple versions of the same engine?

C'mon Dragon...you know I subscribe! I just got my issues of Car Craft and Chevy Hi Performance yesterday...so GMHTP should be following along soon! I'll post it up when I get it. If someone else gets it before me, feel free to do some typing. Thanks.

Technically - that's what they do right now. It could be argued that there are only two V8's in GM's shop. Anything that says "Chevy Small block" or (currently) "Gen IV small block" share the exact same block. like LS2, and LS3 - same block; but different innards, airflow options, and tune. Then you've got the Northstar V8s. which are DOHC V8's...those are apparently being killed off along with their replacement program.

"Just use one v8 for the trucks and one for the cars. If you want different horsepower for different models of cars, you can just tune the engines differently."

If you were to take a basic small block: LS-nothing. and just see how much you could tune it's computer (that's what I'm assuming you're saying)...you might have a threshold of, what...100hp if you're lucky? +50, and -50. Like I said - in basic 'shape'; Something like the L76 car engine, and LS3 share the exact same block. They just have different CR's, airflows, and minor tune.
And it could be argued that the engines in cars and trucks are even the same. Take L76 for example. The only distinguishing differences btw the truck version and the car version is an oil pan, and an intake manifold to allow the car engine to fit under the hood.
So - essencially - there's only one V8 GM modifies for most it's applications.
Well, 2. Cadillac gets exclusive rights to the Northstar.

That's spot-on.

The only thing to add to this is that modifying an engine goes the same way. You can take any motor and, for instance, create better airflow and carefully retune it to add horsepower. Regardless of what motor goes into the Camaro, you can always make it better, so people shouldn't worry so much about which motor GM will drop under the hood. All we need to know is that it will be competitive if not the best in its class and that if we want more we will certainly find ways to make it better.
