That's a fair point, but hiring assembly workers isn't really a capital investment.

Also, I don't think this car is particularly "cheap." I just think they kept their costs low by recycling another platform...but never past that savings on to us. This car costs the same as other cars from competitors that were completely new platforms.
Actually, I think everything you just said, agrees with everything I just said. No?

Probably. Doesn't it feel good to be right?

The problem with the analysis above is simple...

Nobody ends up buying Z28's in that case. They buy Corvettes instead.

Forgive me for saying this, and i know it will offend some, but again:

If the transaction price is equal between the two, the Z28 is going to get murdered. The market does not view the two as equivalent cars, and will not accept equivalent pricing... they'll simply buy the car perceived as more desireable.

In other words, they'll buy the Vette, Camaro sales will suffer, and the car gets killed again.

DON'T compete with Corvette. You just get crushed, even if it's another Chevrolet car.

The great thing about an F4 SS? 95% of the Corvette's performance, for 65% of the price.

Camaros need to beat up Mudstains in the market... not cross swords with Corvettes.

It's good for performance and image... but not for cost.
True. It's expensive, but so are most of the 500+hp motors (especially those hand-built ones) on the market. The GT500's S/c'd 5.4 is no cheaper.

Any idea on what the LSA costs?

How can this be? (Hint - I'm not trying to make a point about weight here)
Since nobody else has taken the bait, I'll throw out a guess: The C6Z has too much power, making it difficult to manage.

What are you trying to say here? The LS3 makes 436hp, not 492hp.

No, they said it's not dead.

See above.

A dry sump system doesn't add much weight at all (maybe 20 pounds?), and the LS7 has lots of forged internals, which are lighter. It also has a larger bore, which reduces the total mass of the block itself. My guess is that an LS7 with a wet sump is very close to the same weight as the LS3.

Also worth noting is that the dry sump system probably only adds 3-5hp... I'd be perfectly happy to have an LS7 with a traditional wet sump and a decent windage tray in the oil pan.

The ZR1 is ~130 lbs heavier than a Z06 -- make your own conclusions about how much of the extra weight is from the engine, and how much extra weight is offset by exotic lightweight materials (e.g. carbon fiber) elsewhere on the car.

I read something recently that said that they stopped bringing Mustangs along during development drives, because the Camaro had already far surpassed the Mustang in every way and they no longer felt it was useful to use them for comparison.

How much are you expecting a supercharged Z28 to cost?

Also, you do realize that if Chevy puts a $15,000 LS7 in the Z28, they get to subtract the cost of the LS3 (~$6,000), right?

Both!

Well, it was the easiest business case. It didn't step on the toes of the "Americans won't buy smaller premium cars" mafia, which killed a clean sheet architecture. And it left Sigma to Cadillac.

But I suspect the pressure was there for a new Camaro. Once the St.Therese issue was resolved and once GM saw the impact the 2005 Mustang had, Camaro was just plain going to happen. If Zeta wasn't around, my belief is, it STILL would have happened.

Yeah, but the GT500's engine is also hand-built whereas I'm pretty sure the LS7 will be the ONLY hand-built LSx engine.

And the Z/28 will probably get the LS8, which is just a little less exotic than the LSA.
LS9 > LSA > LS8

Yeah, me too. Personally, I'll chalk that up to trash talk.

Yeah, I pretty much agree. But if the top Camaro, approaches the bottom Corvette in price, I don't really see a big issue there. Especially if it's focused enough to cater to a specific niche, looking to buy that car specifically..

It's not like saying you want to put a different engine architecture into the car with a lot of capital investment...or putting a s/c engine in requiring a lot of unique components. An LS7 would cost GM virtually nothing.
There is a higher cost for the LS7. It's not like the mass-produced V8 (currently the LS3) and the hand-built LS7 cost GM the same amount of money to produce. If the retail prices for the crate engines are any indication, the LS7 costs more than double to produce what the LS3 does.

It's not.

What I am saying is... that if you took the ls3 and enlarged it to an ls7 it should be around that HP level... Being a production engine, it would be CHEAPER... having still the torque to move a heavier car and affordable for a z28.

Isn't the LS7 about to be killed off anyway?

GM will announce dismal July sales figures and major 2Q losses tomorrow. The big dog Z28 project could die at any time in the near future. GM is beyond downsizing and is begining to panic.
