I won't be surprised if they didn't make one at all.

I would be shocked if they put a LS motor into a 6th gen camaro.

AFM is on the C7 with the manual trans. Why wouldn't it be on the Camaro?.

I don't know why it isn't but it isn't.

Maybe a DI LS7 making about 580 HP, 580 ft/lb of torque?

The Corvette has a steel torque tube between the engine and transmission to absorb the vibrations from AFM, when the engine changes to V4. The Camaro transmission bolts directly to the engine, so there is nothing to absorb the vibrations. On the auto trans, the vibrations are absorbed by the torque converter.

TIL. Thanks.

I think the LS7, regardless of how much I love that engine, is gone now. I gphad thought that GM would simply make a ZL1, light weighted, CC brakes and call it the Z/28. I'm more along the lines that GM will bump the LT1 to 500 similar to taking the LF3 and making the LF4 just for the ATS-V.

So either a light weight ZL1 or a 500 HP 1LE, and I'm leaning toward the latter right now. Mostly because I'm hoping the next Z/28 isn't a $75,000 car.

This pretty much sums up my thinking.

If they are going the N/A Route. I see something ala LS1 to LS6. A hot LT1 if you will. Just based on GM past history of sharing engines, I don't see them making a unique engine for the Camaro. Sorry, I just don't see it.

LSA = 5th Gen ZL1, previous CTS-V
LS7 First Z06, then Z/28
LS3 Camaro and Corvette
LT1, Camro and Corvette
LT4, Z06, ZL1 and CTS-V

The only GM vehicle to get a unique engine was the ZR1 with the LS9.

Also I see alot of people saying 550 or more N/A. It's getting a lot harder to do that N/A with emissions standards.

I think the issue would be valve area and port flow to get enough air in the engine.

Although I doubt this will happen this was a good read regarding the de-stroked LS7. http://www.superchevy.com/how-to/vem...oke-of-genius/

I think we will see an LTx, NA, with CNC heads and special cam. Probably 550 hp/tq.

I don't see a unique engine for the Z/28 either....

...Also, I don't think it will be an issue with how expensive or streetable the Z/28 will be...There are enough models including 1LE and ZL-1 to make everybody happy....The Z/28 will be for the track-rat-only buyer....I think it will have an LT-4 with weight, suspension (including tires and wheels), the kitchen sink, all for performance above the ZL-1 and GT-R....

The 1LE is a step up in performance from the SS with the same engine...The Z/28 will be a step up in performance from the ZL-1 with the same engine...

As expensive as it will be anyway, a unique z/28 engine can't be justified for the small amount that will be sold....

P.S. That monster rear wing shown in the spy-pics tells me the engine will be the highest hp and speed available (LT4) and it will be on the lightest weight Camaro (Z/28)....

See that I could see. Basically the Z/28 takes from the ZL1 and steps it up to insane.

Like I've said for months a 396 ltx variant would make silly power and have a hug powerband. Just think about what a 500hp/500lbft car weighing 50-75lbs less would do on the track. The Shelby twins would have no chance.

How about raiding Cadillac one more time for the Twin Turbo V6 in the ATS, Use RS style Body, Hood Vents from corvette and Carbon Brakes with all the trick suspension and Interior of the ZL1, Light weight, think it would make an awesome track car.

The LF4 in the ATS-V is only better by 9 hp. They might as well keep the LT1 and not have the development costs of adding the LF4.
