The reason I say use the 5.3L is just for heritage sake. It was always a smaller displacement engine compared to the the other models available. Since the 5.5 DI is still a mystery as to what where and when this thing will debut in, the 5.3 (327 CID) can be a high rev dependable motor because of the smaller bores of the block. It is very possible to get 450hp out of that motor and still have the efficiency and dependability we all would expect from a GM production engine. Its just my take and of course I welcome any discussions or rebuttals of it.

YES, that appears to be a Z28!
I would prefer the ZL1 rear spoiler.

In the latest MT magazine it said the Zeta is here for a while, maybe 2016+. Which is good in my opinion. I really dig this design, and apparently so do many others. It also said that GM would release a Camaro of some sort evey 6 months or so to keep ahead of the Mustang.
Very interesting.

X the stripes on the roof, and my choice looks better.

Must have ground affects and a different hood not the ZL1 hood.

Just a quick note on the engine displacement. The reason that the Z28 had the DZ302 was that Trans Am cars were limited to a 5.0 liter max displacement. With no race series to enforce restrictions, there is no reason to not put the 6.2 or even , theoretically (I say theoretically because the cost of the LS7 makes it prohibitively expensive) the LS7 since the structure (block, heads etc) is going to weigh extremely close to the what a 5.3 would (if not slightly less due to less mass in the block since it will have larger cylinder bores).

Thank You!

Stop with the smaller engine stuff. We need to be realistic about what GM can and will do. Look to the Boss and add GM's one or two-uppingness!

Thanks, I'm aware of the 5.0 liter max displacement for the series. The only other engine available that GM has to offer for heritage sake would be the 4.8L and I Just can't see putting a 4.8 in the car that is a little too over board. It wasn't my intention to say that a modified 5.3 would be better than the L99 or LS3 all I am saying is that the whole 5th gen theme has really been focused on heritage. I am pretty sure that is why the ZL1 is named that and not Z/28. The point of the story was that the Z/28 was proven to do more with less. I still think that they can achieve this goal.

Fair enough, however I disagree. Short of going to a ohc, 4v arrangement like the coyote 5.0, increased displacement is, IMO, the only way for GM to get a reliable, efficient and emissions-friendly power plant (even with DI which seems to be good for about 10% more power in a given mill).
As an example, look at the LS7. GM tuned it to 505/475 so that the engine could meet the above mentioned goals. Does it have more in it? Lingenfelter certainly seems to think so : http://www.lingenfelter.com/engine-p...cid-ls7-630-hp
But this is an aftermarket company not worried about having to honor warranty cliams . So, while I completely understand what you are saying about heritage, I believe that without making a OHC LS series, you are not going to see 440+ (warrantied) horsepower out of the 5.3. YMMV

At 327 HP the LS327 didn't fair too bad against the LS7 and the LS3 in the GM performance crate motor shoot out. That is with an Iron Block, 9.5CR, and a recommended 87 octane compared to the others. With a power bump better heads and cam maybe the Camaro with lighter wheels, better suspension, Recaro seats, etc. wouldn't be so bad.

Hmm, guess we have a slightly different take on how a 327 HP LS 327 stacks up against a (minimum) 430 HP LS3 (non hot cam version) and a 505 HP LS7.
I guess I just do not see GM either changing their motor design for this one car or making a motor that is not just short of bullet-proof (as delivered by the factory).

Im pretty sure a 5.3 is 325CI so the heritage thing doesnt really fit.
I still say to use an LS7, it may be more expensive, but that only the difference between and LS3 and a LS7. Plus if they step up production it would help to lower the price.
Seriously, if you were to race against a Boss on a roadcourse, who wouldnt want an LS7 under the hood.
My Z28 would start with a base v6 Camaro, LS7, ZL1 brakes, suspension, drievtrain and wheels.

Number 3 has already made mention that the LS3 is the Camaro's engine in his own cryptic way (except of course the ZL1).

An engine change is a pretty mute point.
Now adding power to the LS3 is open for discussion.

I love the idea of more versions of Camaro...and another car to kick Ford in the axles...I just can't help but wonder how many people would be willing to sacrifice what's necessary to get a Z28 worthy of the name...

No, it's not.

It's on their (SLP's) website.

GM's making a factory ZL1...the SLP car is something different.

About the same that will buy a ZL1.. I personally think that the ZL1 will also be low in the sales department. The GT500 in 2011 will be around 5500, so I would say that you can expect similar for a ZL1.
