I think an LS7 comes in at around $14,000, just as a crate engine...I could be wrong. But besides, regardless of price - if you read Scott Settlemires statement real carefully, you can pick out a very important clue..."Cool car -- but with the piece cost of the LS7 -- coupled with some incredible 'future' powerplants -- forget the LS7 in the Camaro as a production option." The LS7, along with the LS2, are dead...

If the CTS-V engine is indeed the Supercharged LS3, (aka LS9) and it's making 600+ hp, it means that it is a truly versatile engine - capable of huge power numbers....for cheaper then the LS3 (as far as I know). IMO that fases out the LS3 completely.

A: The LS9 wont/cant be cheaper than the LS3 because an LS9 starts life as an LS3 and then gets supercharged, a supercharged version of any engine is never cheaper than the engine it is based upon.

B: The LS3 isnt phased out because its brand new, it debuts in the 2008 Vette in a few weeks and I would be incredibly shocked and completely baffled if it wasnt available in the Camaro.

I know that there has been talk of not being able to supercharge an LS7, but vortech decided to do it anyway...

http://www.vortechsuperchargers.com/...&section=Media

6.5 lbs. of boost, and 630 hp at the flywheel, 57X (570-something) at the rear wheels...(wow)

Vortec can supercharge anything because they use a centrifugal (sp?) style supercharger that just adds power on the top end, but it does little-to-nothing on the bottom end.

Has anyone else thought that the 430hp of the LS3 is ONLY 70horses shy of the LS7? Doesn't it seem like its a pretty short leap from 430 to 500? I bet we could easily 450hp by the time the camaro comes out... and that is pretty darn close.

Although I would LOVE a 427 Camaro, I think we can bet on an LS3 powered Camaro with 450hp out of the gate.

Now, about that supercharged LS3... THAT's the motor to have. Why? Let me tell ya:

-Probably forged pistons (to handle the boost pressures)
-Forged connecting rods (more beef)
-Forge & Nitrided crankshaft (stronger and longer lasting)
-Improved cooling
-Bigger valves
-Reinforced engine block (skirt & main bearing support should be beefier)
-Beffier Trans (probably same improvements as are seen in the 2008 'vette)
-Stronger rear diff?
-Limited Slip Diff for sure...

This is all speculation, but its based on best-practice, and historical reference... feel free to add in any improvements you might expect between these two engines as well!

Either way, I'm not sure if I'm qualified to own it, but if the LS7 comes out in 5th Gen my money's down. Otherwise its an LS9 Camaro SS for me!

LSx I agree with you 100% on that one. I even read that supercharged LS3(LS9) was built to withstand to handle boost pressures, even said something about reenforced cylinder wall...tell you what Im stacking my pennies for that LS9.

But you all know what that means, right??? After reading all the additions, all I see being added (besides the goodies) is $$$$$$$$$$. I guess that's expected for "super, crazy fast", though.

The LS3 incorporates a few LS7 derived bits and pieces. Personally, I would prefer an N/A car, so I'd skip the supercharged version and stroke it out. I'm surprised that no one's mentioned a stroker at all, given the fact that the 383 has been so widely used

This is true, but it would be FAR cheaper to buy all this stuff from the factory up front, rather than trying to add it later... yes I know some will debate the fact that the aftermarket could be cheaper, but when you factor in time/warrantee/quality etc. It's still far cheaper.

Oh, I completely agree! It would be cheaper to get it all from the factory and have it done RIGHT. I could see it costing more having an aftermarket company rebuild the engine (parts and labor). I would prefer to buy it already built from the factory 100%. I just wonder how much more GM would charge for the beefier engine and other upgraded parts.

I thought that part of the reason the LS3 was so much better than the LS2 was that is was already "beefier" (stronger, whatever you want ot call it).

Hey all. I found this while trying to find more info on our car. I don't know how accurate they are and if this isn't allowed, go ahead a delete this post. The site is at http://5thgen.org/forum/showthread.php?t=1100 According to them the LS7 is a big No.

Yeah, I agree with them the LS3 s/c'd will probably remain Corvette. I've been wrong before (just not often). It could find it's way into the Camaro, but I receed my previous post in this thread, and agree with Tag, the added "really-tough-stuff" parts in the LS9 will crank up the price too much for it to be Camaro-possible. SO look for a minor hp increase with the SS package (30-50).

If the SS is the top dog package. Not sure about the validity of the rumors that the 4th gen Z28's hp ratings were downplayed in order to make the SS package seem like a bigger gain. Hope that's not the case this generation

Now that you mention it, I have heard that the difference between Z28 and SS was almost inperceptible....(in the 4th gens)

The crazy thing is - that these engines can be tuned up/ or down, indefinitely! look at the G8: it uses a 6.0L engine, yet only puts out 362 hp!!?!? What ?....and why? when the LS2 used to put out 400...

The question stands, but we must step back and remember, that 362 hp is a lot of power...

EDIT: From now on, I'm speaking in the past tense with the LS7 and LS2...

I never said it wasn't possible to have the LS3 supercharged (or LSA) in the Camaro. I was just saying all the upgraded parts would make it cost THAT much more. It is possible...it is just more cash...

Are there any other differences to the 6.0L engine in the G8? Does it have different heads, cams, or intake? All those things could cause it to make less power per liter than the LS2.

When I opened up my latest edition of "Pontiac Performance" I was eventually assaulted by this:

(The buck-toothed beaver that is the G8)

I have to say I was dismayed to read this:
Quote:
G8 GT models raise the horsepower stakes with a uniquely configured 6.0-liter OHV small block V8 that pupms out a whopping 362 hp and nearly 400lb-ft of torque.
Excuse me, but WTF??!! The LS2 in my rebadged Holden Monaro puts out 400 hp @ 5200 rpm and 395 lb. -ft. of torque @ 4000 prm. As Rock36 asks, what can "cause it to make less power per liter…"

I like the G8 a lot also.

But I'll admit, that Lumina SS on the front page of GMInsidenews has an even more appealing look to me.

Wow! That actually reminds me of the Acura TL. That is a very, very appealing sedan. It has a more "up scale" look to it. About time, GM!!! GREAT JOB!

Yup - there are definitely more aggressive styin' cues to be had from the Lumina than the G8 beaver saying, "…duh."

I really don't think it's an LS2 in the G8, it's that other...what is it the L76 /or L98, or something like that.

And I'm sure that there are differences, such as heads...etc. The site didn't get into detail, and I didn't dig THAT far.
