at least we get the real numbers nowadays LOL, i just wish it was like the old days where there was a racing series that made production of these cars essential =/ at least we got all three makers in competition to give us, the consumers, the ultimate win

By the way...you gotta wonder, where will the line be drawn in these cars? 600hp cars from the factory, jeese...what about 800? 900?...dare we cross quad-digits 0_0 LOL

OH, i just learned the LS7 concept Camaro that was shown at SEMA actually had a "slightly modified 586hp LS7" so obviously its very simple to push this thing beyond the LSA on all motor...ehh, looks like im swaying back in favor of the LS7 powered Z/28 again, im sorry there's just something about "all motor 427 Camaro" that sounds so magical

Maybe it'll be a new engine, the LSB
same design but uses a 1.8L whipple or KB.
more compact, quieter, more efficent, equal if not better boost and cooler charge.

hmmm
also hmmm

How about a new Z/28 specific engine? A smaller displacement, higher revving engine than the LS3 which would also help on weight savings and give a nice throwback to the old Z/28s (thats another thing i didnt take into account, weight of the LS7 verses weight of the LSA)
Well in Grand AM and soon in the American Le Mans there are 5.0L LSx engines that produce 500+HP that rev to about 7000k+. But that throws the NVH, fuel econonmy, refinement, emissions, and all that good stuff that you never heard of in the sixties out the window.

In the end all LS engines are true marvels of modern engineering anyways xD
Totaly agree!

Ah man, now you got me thinking about how awsome it would be to have the old Z/28 302 back with 500+ horsepower xD

Here's a link to an article with an LS1 built to 302cid as a tribute to the first gen. 302, 435hp @ 6,000 RPM. I could see something like that with higer rev limits going 500HP plus.

That's amazing, LOL, i wish they'd do builds like this for the new Z/28, although with 435hp thats just like 10 extra over the LS3 so they'd have to either up that or else put a LOT of emphases on lightening the car, either way thats a really cool article

The Z-28 Motors of Old

Assuming that the Z/28 will not just be cosmetics and will be, instead, performance based, what available options, motor wise, are there that would be in the small block category (sorry, I have not kept up with GM motors)? I like what Vega had to say about the 302's. The Z/28s of old were relatively light and nimble. Putting 427 motors in them would make them as nose heavy as the GT500. A small block would shave weight and still leave the potential for supercharging it to power levels that are not destructive to the motor but very impressive on the track (I am thinking road course here). Thanks in advance for any light you can shed for me on the motor choices.

Right on man, i hear ya...i know i know, spare me another "The LS7's on its way out man" speech, lol, i just honestly think the LS7 would be a better choice, and we know GM is considering it because look what they took to SEMA, the SEMA LS7 Concept Camaro, it wasnt an LSA Concept Camaro, LOL, and that car netted 586hp with a simple hotcam swap which we know GM can mass produce the engine like that...plus i mean who wouldnt love to see the Z/28 own the GT500 with an N/A engine? Not to mention the LS7 is 100+lbs lighter than the LSA (after liquids added)

Actually its an interesting note that the LS7, while being the biggest of the three, is also lighter than the LSA and LS9...although i would very much love to see an extremely light LS302 return as mentioned earlier (thanks to clark17357)
Really i have just a few beefs with supercharging and those would be that supercharging focuses on more power ar higher RPMs which i preffer more low end power and torque, i personally cant stand supercharger whine (although ive heard the LSA has eliminated this), supercharging adds a lot more weight than most people think, often making it heavier than just a large bored N/A engine (such as the LSA vs. LS7 discussion), and lastly idk if this is still true for the LSA and current engines but dont supercharged engines tend to have more hesitation between the pedal reaction and the power reaction? (correct me if im wrong here, id rather know the facts than just have oppinions LOL)

Depends on the supercharger, roots give low to midrange torque with flat torque curve, centrifigals give more top end power. Since the LSA/LS9 uses the new gen roots supercharger TVS series they are quieter than the old gen superchargers. Superchargers power is instant and have no hesitation. Some folks don't like roots because you have instant power on the low end and makes it harder to put the power down.

I have a supercharged GTO.
