I've seen alot of different engines being thrown out there for what could potentially power the V8 Camaro(s) and replace the LS2, such as

LS3
LS4
LS8
LS9

Are any of these engines far along into development, already developed, or are they just an engine concept.

As of right now it seems fairly unreasonable to assume the Camaro will be getting the LS7/LS9, however is the LS7 already being phased out into the next generation.... seems pretty early for them to be already throwing away that motor, and for what reasons?

Can anyone guide me to where I can read more about these new engines such as displacement and possible HP #'s for the LS3,4,8,9.

Is there already an engine set to replace the LS2 or is everything still up in the air?

 

The only thing I can say with certainty is the LS3 is the sucessor to the LS2 . Im getting 450 hp with active fuel management . I dont know what to make of the LS9 yet . I know its going in the Vette , but at what level . I kinda wanna think the LS9 is the successor to the LS7 in the Z06 , and not a new engine for a superVETTE . Ive heard GM has 3 new 6.2L LS supercharged engines coming , including the Ls9 . One with a blower , no intercooler , 1 with a blower and intercooler , and the LS9 which is a high output , blown and intercooled .

If thats true , Id about bet the farm on the mid level supercharged engine being the top Camaro powerplant . I thought that ever since I saw the concept had a cowl induction looking hood .

Theres guys here smarter than me though , hahaha ...Im just making a educated guess .

The LS7 will be replaced by the time the Camaro roll around from all I can gather . And the LS4 is a FWD only engine .

 

I'm equally confused, but have been able to gleen the following (mostly rumors):

LS3 - Will replace the LS2 in 2008/9. I've seen claims of 6.0L and 6.2L and about 450hp. Heads are supposed to be compatible with LS2. It will also have AFM. (Incidentally LS3 was the designation for the 402cid big block of 1969-70.)

LS4 - Current 5.3L, 303HP FWD V8 with AFM in the Impala and Monte Carlo.

LS8 - I've seen claims that its bigger than the LS3 but smaller than the LS7; and a few suggestions that it may be supercharged. Still not sure where it fits in. (I 've seen an "old" RPO sheet that showed LS7 as a 6.4L HO. Since LS7 eventually came out as a 7.0L, perhaps the 6.4L was relabled LS8? Just speculation on my part, don't read anything substancial into this.)

LS9 - The next Super Corvette motor. Some have said its a supercharged version of the LS3 displacing 6.2L. I've also seen more recent suggestions that its a DOHC 6.0L and supercharged. Regardless, its supposed to be cheaper to manufacture than the LS7 and around 600hp.

I think we're going to see more and more supercharged small blocks in the not so distant future.

 

Okay, you guys are totally getting me excited with those engine options, i actually giggled like a little girl. Okay creepy little girl references aside, what do you think the 0-60mph times are gonna look like? The current GTO advertises high 4's and it has a similar set up right? The challenger is trying to say it does it in 4.5 seconds and it weighs over 4100 lbs and only has 25 more hp. The mustank's is 5.3'ish and i think the current EVO's and STI's are bragging about 5 flat, so it would be nice to be able to smother those guys with a car that actually costs the same or less. I know most of you guys don't give a rip about 0-60 times but for a college kid like me who CANNOT get pulled over, 60 mph is a nice safe run.

 

No LS7s or successor. Perhaps in some limited model well later (2010? 2012?).

Pick the biggest displacement small block offered in GM's trucks that particular year, and you'll have the top likely Camaro engine size (with performance enhancing additions).

Management feels a mid level V8 is needed to boost sales volume. This only means the 5.3.

There is also going to be a V6. Fbodfather already gave a good hint which V6 it isn't, leaving the V6 it is.

As for horsepower, expect more than the LS2 for the top engine offered in the lineup. It's probally a safe speculation that the 5.3 will be producing LS1 power levels. It's probally a safe bet that whatever V6 GM picks will be competitive with the 250 horse V6 Ford plans to install in the Mustang very soon.

Acceleration times aren't even worth speculating over till we at least have a weight estimate of the Camaro line. If you are expecting Chevrolet to produce a $25,000 car that's going to smoke a Corvette, that's not the object that's smoking. A good "pie-in-the-sky" guess might be a $25K 5.3 Camaro as quick as the last LS1s, and a $35 Camaro that runs with the $40K GT500.

But a word of caution: A car wider than the old and large B-body Caprice-Roadmaster-DeVille of the 1990s isn't going to exactly be a featherweight. Doubtful in top trim that it's going to weigh as much as the Challenger, but it's pretty certain to be heavier than your old Camaro SS or the neighbor's shiny new Mustang GT.

 

You guys are close...very close! Amazing....where do you get your info?

 

I'd hate see to see a supercharge Corvette. NA all the way!

Long live the 427 SBC--add VVT and 3 valve heads. I really, really want this on the Camaro

 

So Guy, sounds like we are looking at V6, 5.3L and LS3 then.

Piecing together what I've read over at digitalcorvettes.com and in the new GMHTP, LS9 is basically going to be the Blue Devil motor, 650hp, blown & intercooled, LS8 will be lower HP also intercooled, could be yet a third non-intercooled version, and then below that you have the LS3. All of these are 6.2L basically car versions of the new L92 Tahoe motor, which includes heads that are near exact copies of LS7 heads.

I'm assuming these will also get DOD and the variable cam timing from the L92 as well.

 

If it doesn't get a SC engine, I can see the top Camaro V8 being a 6.2 with an LS7 level of tune.

Below that, I can see a 6.2 tuned more conservatively but with similar output as the current LS2.

Below that, some version of the 5.3.

And below that a V6.

Or, perhaps a more powerful V6 that would replace the last two.

The debate we should be having is, will the midlevel motor be a 5.3 or a 6.2?

This needs it's own thread.

 

Not if the supposed 5.3 5th gen is only making LS1 power levels. The 5th gens added girth, is going to tip power to weight in the 4th gen's favor, and I am fairly certain the 5th gen's IRS isn't going to get the car out of the hole as well as the 4th gen's crappy 10 bolt.

 

Ask and ye shall recieve.

 

I'd like a 5.3L with a 6 speed for myself.

Should give a good amount of go and a decient highway gas mileage number. Not all of us want/need 400+ HP for a daily driver

 

I would like to say a 5.3 mid motor , it seems logical . But man , the way HP figures are looking TODAY , if the trend continues ....there not gonna be shrinking . I tend to think more to non-logical side of the fence .

3.9 base
6.2 LS3 base V8
The mid level intercooled supercharged 6.2 for the top model . LS8 ?

 

Yes a all aluminum 5.3 with a preferred 6 speed manual trany packaged in a mid level convertible package. Perfect for this old mans cruiser
