Actually the LSA and LS7 now cost roughly the same amount if you're looking at purchasing a crate motor.***
I think a better option would be instead of a hand built LS7 would be to create a production line version (Heck call it LSZ), or even the "hot-cam" version of the LS3 (which is good for 480hp).
I think its going to need around 500hp to keep up with Joneses as there will need to be a balance between cost and weight reduction to keep the price down. Which is also why I'm not against a twin-turbo V6.
*** The LS7 is actually $3000 less than the LSA

I just dont' see GM changing any of the engines in their lineup. We know that GM powertrain doesn't just drop in a new cam or change the heads on existing engines without making them a new one. LT1 to LT4 or LS1 to LS6. And when they have done this it was for the Corvette. With the LSA, LS7 and LS9 I don't see them changing anything for the LS3. So it either gets more power from yearly updates or stays as is.

If GM wants to make a statement with a competitor to the new BOSS, throw the LS7 at it, and price it competitively. The people at Wixom have to fill their time somehow.

The LS7 wouldn't save much cost over the LSA (about $3k), however a theoretical Z28 doesn't need all the bells and whistles the ZL1 has either. In theory, you could start with a 1SS, upgrade the brakes, wheels, suspension, add a carbon fiber hood and rear deck lid, and drop in the LS7 and 99.9% of the Z28 buyers would be satisfied.

Strip the rear seat (and OnStar ), take the lighter exhaust from the ZL1, light 5 star wheels (with the iroc influence), add spacers and lower the car 2 inches to close the wheel gap, and use a new cam that revs to 7k RPM (with less tq and more hp) for some LS variant engine. The lower tq would keep its 0-60 time below the ZR1 (and reduce warranty liability for the manufacturer from customers that like to hard launches) and the sound of the cam would really make the car IMO. Obviously a mild exterior change like a ducktail spoiler.
Some companies think of their car line-ups as:
base model: X hp and $Y
mid model: X+ hp and $Y+
mid model: X++ hp and $Y++
I think GM should avoid this boring formula, and make it unique. Make its performance different, but not necessarily a lesser. Comparing the SS to Z28 to ZR1 should be like comparing apples to oranges to bananas.

Unfortunately that seems to be Chevy's attitude on the Camaro, wait and see what Ford does then build a car to compete with it in 3 years. Why can't the Z28 be supercharged? Why does a car built today have to copy the formula from 40 years ago? I did see an awesome 1st gen Z/28 2 weekends ago up near Greer SC that had brand new tags on it from NC, it was black and sounded meaner than anything I have ever heard in all of my years. The guy in front of him and me behind him both gave him thumbs up, it was wicked, deep and powerful sounding. He gunned it a few times and it didn't look to be stock by the rapid rate of acceleration.

Re: The latest word on the Z28 nameplate...
Here is what I would do to make a Z28. Drop the LS7 in there. I am guessing its 100lbs lighter than an LSA. Go to 19 inch wheels to further save weight but keep them wide as the ZL1 and no run flats. Carbon fiber hood, trunk lid, fenders and seats. Dump 4 of the 6 airbags and a minimal stereo system. Use Aluminum for suspension pieces including shocks. Make the brakes smaller. Do we really need 14.5 inch rotors? 13.75 in front 13 in back and both would be 2 piece. Go to a 3:73 rear gear. Lightweight Ti exhaust.

GM already sells the hot cam version of the LS3 as a crate engine (LS 376/480). All they would need to do is have it certified for Camaro, something they can easily do within one year. Furthermore GM already has the E-Rod LS3 crate engine CARB/50-State emissions certified as a direct replacement engine, and is working on similar certification for an E-Rod version of the LS7. (Yes that LS7.) Dropping either engine in a production Camaro (LS 376/480 or LS7) is a simple as doing the testing and filling out the paperwork.

Give it the ZL1 rear spolier. And if we are lucky a nose like the Jay Leno Camaro. Real Z28 stripes to the end of the nose!
Focus on weight savings. A nice set of lightweight wheels fit for the track would go far on ZL1 spec rubber to earn this Z it's slash and stripes!
More Grand Sport and less Z06.

Here's what I think Chevy should do for the Camaro in 2012.
LS- Base v6 Eco Camaro(replaces the LT), LTT V6 -312hp 30-31mpg on the hwy.
RS - LFX 330 hp V6, with SS tires, spoilers, and a Suspension & track package.
SS - (Mustang GT fighter) LS3 426hp V8
Z/28 - (Boss Mustang Fighter) 450-455hp LS3 V8, with ram-air, exhaust and track package upgrades.
ZL1 - (GT500 fighter) 550+ hp LSA V8

We really don't need an "Eco" Camaro. The DI V6 makes great gas mileage as it is for an almost two-ton muscle car.
I'd still like to see a turbo V6 in the line-up, however I doubt I'll get it.

Re: The latest word on the Z28 nameplate...
I would like to see the Z/28 have:
The dry sump LS3 from the GS Corvette. All the Vette guy's racing wet sumped cars were eating motors up. It would be nice to know the motor actually could survive being road raced. An LS7 would be nice, but it would push the price of the car up too much.
A light weight flywheel with a dual disc clutch. It might take a little getting used to, but the motor would "feel" a ton more responsive and free revving.
TR6060 with a unique gear set aimed at road racing.
The heavy duty driveshaft and rear axle assembly from the ZL1, including the 3.73 gear ratio.
Also steal the brakes from the ZL1.
For suspension, just install the complete Pfadt (or Pedders) catalog. The magnetic shocks are awesome, but they lack user adjustability, a must if the Z/28 is to be a serious track car.
Lightweight wheel and tire combo.
Throw the track mufflers, from the Chevy parts catalog, in the trunk as an end user installed option, they aren't legal in some states. They would add horsepower and save weight.
And last but not least, shed weight where possible.
