The LS3 has two supercharged variations produced by GM right now, there's the LSA which is a mild supercharging option added right to a stock LS3 and there's the LS9 which is a heavy duty supercharging added to an LS3 build with more durable forged internals, so first i say if you're gonna offer a supercharged LS3 in the Camaro, why half-ass it? Especially in the durability department. NOW as far as the LS7 goes, it of course is the LS 427 which would be an AMAZING marketing tool. Offering a 427 in a production Camaro is any muscle car lover's dream, also the LS7 has 505hp compared to the LSA's 550, but the LS7 is an all motor car and can most definatly be re-cammed to the 550 mark and new heads could put it to around 600 even (its been seen in the LS3 already, GMperformanceparts.com is offering a cammed and head-swapped LS3 with around 480hp so we know it can be done and mass produced that way) Also the LS7 has forged internals as well, another major plus

So here's a list of the advantages of offering the LS7
1. Everyone has always wanted a 427 in their Camaro
2. It can match the GT500 competition without a supercharger
3. It has forged internals so it will be more durable than the LSA
4. With very slight mods it can easily match or surpass the LSA's horsepower
5. If you're not content with your rediculous power, you can supercharge the LS7 to god knows where, LOL

The LSA has the steel crank from the LS9 though. It won't match the 540 horse' GT500 without more mods'. It's already being phased out, to my understanding too. I would like a 427 in my Camaro though

it would be better for them to introduce a new engine then use the ls7.

bring in the DI V8 (Gen V motor). better then lsa or ls7. could have smaller displacement then ls7 put out more hp and tq.

That would still be very cool

In summary, it won't happen.

As long as it's close to the 500, I think it'll do well in this segment, personally.

Now I know I'll just do bolt ons on my car cause I'll probably end up trading it in for the Z28.

I agree with this.

Maybe...but the other side of the coin is dealer who won't mark it up...like some of our dealer friends on this site.

I don't think an LS7 Z/28 would have enough hp for it to be competitive to the GT-500, without cutting atleast 300lbs of wieght. I know GM can give the LS7 more power though without F.I., I have seen N.A. Z06's with 550hp at the wheels. There is still alot of untapped potiential from the LS7, it is afterall 7.0 ltrs of displacement.

I don't get this, where is this Idea coming from that the LSA that is equipt with a supercharger, is cheaper than an LS7? I know the Gen V small block is coming, but have anyone actually considered that a D.I. version of the LS7 would be a possibility. Just it would no be called an LS7.

Lsa is a supercharged engine. You don't call it an Lsa if there isnt a supercharger.

[Speedy1975]

What moron would ever pay $100K for a Camaro?

If they're gonna do this thing it'd behoove them to make it a standard car to order, not some super limited deal.

I won't even try to say that the LS7 is tapped-out, power-wise, however, there's the problem of drivability/pleasability and emissions to think about too. I could remember reading how the 'Vette engineers were pleased at how smoothly the LS9 idled as opposed to the LS7; the LS7 needs those huge CNC ported heads and pretty large cam to make the 505 horse' that it does, while the LS9 doesn't need a hairy cam and I think emissions are effected less with adding a supercharger (I believe a lot of it has to do with overlap and cam timing, from my meager understanding). I think it boils down to it being easier to slap an LSA, that doesn't require hand-building like the LS9 and LS7, nor require any exotic materials, like the forged LS9 pistons and bearing caps and the Ti rods and intake valves for both. I think it's just easier/feasable to get a smaller FI'd 6.2 to get through emissions cert' than an even hairier LS7 with a bigger cam.

JMVHO.

I know, my point is that there is an arguement that the LS7 is too expensive to be in the camaro than the LSA, but the LSA IS MORE EXPENSIVE than the LS7. So I have trouble seeing how that logic works, But I do see the LS7 not being placed in the Z/28 because it does not have the Hp required to be competitive to the competition since the camaro wieghs 3860lbs. See what I am sayin.

[ShnOmac]

LS7-$13,649.95 with out SC

LSA-$14,295.95 with SC

Prices from paceperformance

[radz28]

Then you have to worry about all the dry sump parts and where to place them and get them to fit, too...

LSA it is people.....

Then again who knows what may be out in 2 years... muahahahaha

I don't think so. If they can release a car near GT500 performance for significantly less, they'll capture a lot of the GT500 market. Anyone who wanted to outperform a GT500 can either spend money right away for a Corvette, or buy the Z28 and mod it down the road (or add GMPP options at build).

That also eliminates the worry of the Z28 cannabalizing the Corvette market, which means they wouldn't need to limit production.

The more I think about it, the more I think the Z28 fits best as a GMPP-upgraded SS, sitting around $40k-$45k.

[Robert91RS]

Cost of the LS7 and LSA are within pennies of each other and the LSA has better emission characteristics. Plus the LSA is capable of more HP per dollar of mods than the LS7.

To clear up the differences in the LSA vs LS9: The LSA has a heavy duty block(just not as heavy duty as the LS9), a forged crank thats a little more ecenomical than it's brother, PM rods rather than forged, hypereutectic piston instead of forged, LS9 oil piston squirters, a 1900cc supercharger in place of the LS9 2300, a wet sump oil pan vs the LS9 dry sump and the LS9 style HD cylinder heads. This means the LSA is one hell of a motor. That being said I too would rather see an LS9 running at a lower PSI than the ZR1 so the owner can turn up the boost without ANY fear of damaging the rotating assembly. But I suspect the 7k price difference is the root cause for GM's decision.
