Look, guys, there is no reason to be all pissy. If GM wants to put a N/A motor in the Z/28 its going to happen. Just because it didn't meet the Z06 goals doesn't mean it wont be at the Z/28. Look at how many people are happy with the GT350 and Voodoo.

You act like making new heads/intake is a hard job for the team at GM to do. They likely went through thousands of CAD designs before they settled on the ones for the LT1 and they know what will work better to get more power.

With a limited edition/production model, CAFE really doesn't matter near as much. They will sell as many Silverado in a DAY as they will the Z/28 in the whole year.

I think you're agreeing with me. I'm sure they went through dozens of variations to get the final LT1, and know of ways to get more horsepower. So if the Z/28 stays with the same LT4 as the ZL1, CTS-V and Z06, the only logical answer is GM didn't want to build a higher output n/a LTx.

They created a package that fit in the smallest engine compartment to power a minimum of three very different cars. If you want to say they did it for the Vette, I won't argue. GM is approaching 10% margins. That is a milestone for them. The more money they make, the more money they have for R & D!

Again, they don't have to go through the whole validation process with just a modification of an existing engine. It isn't a whole new one.

They aren't making money on the Z/28. Just aren't. Ford isn't making money on the GT350 but every single Mustang GT they sell to those who don't buy the GT350 is cash in the door.

GM sold about 49000 Silverados last month. That's about 1650 trucks a day. That doesn't even count the Sierra, Colorado OR Canyon.

That is there goal, but to date it has not happened,the 2015 Z/28 is coming on 2 years out and that was 1500+ car and there not sold out, dont get me wrong i want them to sale as many as they can, i think its the best Camaro.

Does building a Z/28 meant to compete with the GT350R mean it can't be better in every way and the best Camaro possible?

And Corvette had developed a N/A engine for the C7Z but it didn't workout because of emissions. What is stopping Team Camaro from picking up where it was left off? I doubt Camaro team is benchmarking the same HP levels as the C7Z was. Not out of the realm of possibility.

Possbility of a sohc or dohc? LT5 type. Less then 6 liters but able to rev.

More so dohc.

What's stopping them is bean counters and bosses. I'm sure Team Camaro wants to do a lot but getting approval is a whole different ballgame.

Heat soak is always an issue on supercharged engines.

Until it isn't.

I find it kind of interesting that so many Camaro forum members completely discount the possibility that GM has another high performance V8 engine that has not been put in a production car yet. People have already mentioned that the LSA evolved from the LS9. Would it really be that crazy to have a LT9 for the zora and a LTA in the Z/28? I don't know what the official name of the motors will be but you can bet that LT1 and LT4 are not the only configurations that we will ever see for the new LT V8.

Speaking of sales numbers, has anyone noticed what the hellcats have been doing.... hint, hint,... I'll bet some of the GM execs have noticed....they are selling everything they can build.

I'm wondering how long it will be before we get all the details on this new Z/28 motor. If you look at the 2016 SS Camaro and the performance level this car was brought to and then look at what is in store for the 2017 ZL1 with the LT4.... I'm betting someone learned that the only problem the gen5 Z/28 had was it didn't have enough HP to justify its price point in the line-up and this time they are going to make it right. We will wait a bit for the reveal but the Z/28 is going to be a twin turbo V8, it will be the top tier Camaro in EVERY performance measure. And I suspect just like the modern Porsche and Ferrari owners, anyone that gets a chance to drive one will forget about how great N/A used to be once they feel the torque and sheer power of a good set of twin turbos.

Of course this is all speculation because most of us don't really know anything...

Weeeeell now Car and Driver is speculating on a Corvette ZR1ish model to precede the midengined C8...

[Bhobbs]

How do they plan on controlling more power in the C7 when the Z06 already struggles, or so reviews have said?

Probably have the A10 too.

There will be plenty of room for turbos on this mid-engine car. I'm fairly certain that this Zora and this new Z/28 will share an engine that GM has not yet revealed the details about. Don't know which release will come out first but I have been saying for a long time... the new Z/28 will have turbos..... and it will crush everything in its class that has been built to date.....everything.
