I'd look for a 350hp camaro and leave the factory 500 to the corvette. If they match this to the beloved vette in factory horses.. you're going to have some pissed off owners! I look forward to a good time in these forums... lata!

Nah, the Corvette guys will be safe... with the new ZR1 pushing 650hp it elevates the Corvette high enough to allow a 500hp Camaro underneath. Plus, the Z06 weighs hundreds of pounds less than the Camaro so even WITH equal horsepower, the Corvette will still be MUCH faster in all conditions.

350hp just isn't enough. You can probably get that from the V6!

500hp is the competitive figure that Camaro MUST achieve to be credible. The new mustang GT (2009) will be pushing 380hp (according to the rumors) and the Challenger SRT-8 will be pushing 425hp (prolly 450 by then) so the Camaro SS really HAS to have over 450hp.

They have already announced that they can get 500hp from the LS3 Block with GEN V heads on it, so its already a done deal from a technology point of view... now its just about marketing, sales, and pricing. Since its still a common block I don't expect a huge price increase.

I'm pretty comfortable with the idea of a 475->550hp Camaro SS coming out in 2010 for around $40K. Probably a little less, maybe a little more. All the technology is pointing in that direction.

They have?!?!? I missed something.

Ah, my apologies... I went back and re-read the original article and I realised that hadn't actually announced this as the GEN V technology. I guess I jumped the gun a bit...

My bad...

I _am_ assuming this is GEN V hardware on display, just not announced as such. What IS true is that they HAVE shown a 6.2L engine making well north of 450hp in a current vehicle, using existing (and presumable reliable) hardware... this is a good sign all by itself.

The camaro engine won't be small. It would look silly under the hood. I think they designed it for big displacement, and thats what we are going to get, which will include the Gen V technology.

Oh, no. I meant about the "LS3" being used for the prototype...I read back thinking WTF? but, yeah - it's gen V, and they've as good as announced it as such, too. "If it happens we'll have to release it as a whole new generation achetecture."

I don't know if this is a response to what I said - but it could smaller. What they're saying is that with this new Gen V design - the DI naturally makes more power - so to get the same power that you get out of, say the LS3, then you would need a smaller-than-LS3 engine...you see what I'm saying? Smaller is actually better in this day - especially if you can coax more power than before - because smaller generally means better fuel economy.

The block itself is probably based on the LS3, or maybe even the same....that is as far as bore, stroke, and cylinder spacing goes. The basic dimensions.


This new GEN V engine block might still be detuned to come in at or below the output of the LS3 if the Vette still has that engine while the Camaro gets the new engine.

Yes I was responding to you...

I really think its going to be a big motor. But thats just what I think, and HOPE!

[Rock36]

I was thinking about that statement too

"The greater specific output provided by DIG also would allow for greater engine downsizing, thereby improving fuel economy even further"

I was just thinking about the same size engine based on the generation, but I makes sense we might in fact see a smaller engine (Perhaps 5.7L or 350ci) that is still making over 400hp.

That would actually be pretty cool. A smaller engine would drop a few pounds off the overall weight of the camaro too, improve the F/R weight distribution, etc.

[Mr. Wyndham]

Yeah I was thinking about a 350 DI engine, too. It would be an interesting base V8...

No doubt there will be other 6.0L's, I agree. But the LS2 version IS dead; the LS3 replaced it. The L76(which is a 6.0L) is still kicking, and I'm 100% sure there will be a 6.0L Gen V engine, too. It's still a "small-block" engine lineup, so they can't go too big.

Too true...

[AConn]

Please be 500hp stock!

[Rock36]

Just in case anyone was wondering, because I did......Displacement alone doesn't classify an engine as a "small block" or a "big block"
Here are the best definitions I have been able to come up with from http://www.chevytrucks.org/tech/block.htm

Just some good general knowledge.....

Short Block: An engine WITHOUT the head(s). Usually includes the crankshaft, camshaft, and pistons.

Long Block: An engine WITH the head(s). Usually does not include the oil pan, valve covers, and manifolds.

Small Block: The smaller of a manufacturers two series of engines. In the case of Chevy, the small block includes the 262, 265, 267, 283, 302, 305, 307, 327, 350, and 400.

Big Block: The larger of a manufacturers two series of engines. In the case of Chevy, the 366, 396, 402, 427, and 454.

Notice the overlap of small and big block displacements. Note also that a small block can be a long block. The terms define different characteristics of the engine.

I also have read that it has to do with the actual spacing of the cylinders. The LS7 is still considered a small block engine and it is a 427ci

[Rock36]

As for a smaller GEN V engine going into the Camaro, I was thinking in terms of there still being a 6.2L LS3 vette out the same year.

A smaller GEN V DI engine (doesn't necessarily have to be a 350ci) would allow for GM to put the new technology in a new platform, and still keep the Vette with a bigger and likely stronger (on paper at least) engine.

[Mr. Wyndham]

+1 that's what I was thinking. If they put Gen V into the 'Maro, then that's probably what they're going to do. keep the base V8 at 370 +/- hp, and then use an equivilant of the Vette engine as the Top-trim(like they've typically done)
