Just read this on MotorTrend:

"The 2014 Chevrolet Corvette Stingray is finally here and it’s a significant update, but it’s just the first step. We’re already hearing whispers from the Warren plan about the next Z06 and ZR1.

2013 Chevrolet Corvette ZR1 front three quarter 1 300x187 imageWord is, the next Z06 will keep its monster naturally aspirated 7.0-liter engine, but with even more power. In fact, we hear it could jump from today’s 505 hp to as high as 600. The decision won’t be made, though, until they get the final number for the next ZR1’s supercharged V-8. That engine, we’re told, will be an evolution of the new LT1 V-8 in the base C7. We can only hope it will revive the LT5 moniker of the original ZR-1’s engine. The 2013 Chevrolet Corvette ZR1 is shown at right.

The Z06/ZR1 output logic basically works like this: If the ZR1 makes 675 hp or so, the Z06 will get 550. If the ZR1 cracks 700 hp, the Z06 will crack 600. Anyone who knows GM knows how this works: The top-dog Corvette will always be protected, even from its own variants.

The Corvette team has so far refused to comment on the next Z06 and ZR1, but we’re told the first variant, likely the Z06, is at least a year out so as not to trample on the base car."

Well there was an earlier post, also from supposedly Motor Trend that had this to say;

"According to Motor Trend, the third-generation Cadillac CTS-V is racing around the confines of Milford in both twin-turbocharged and supercharged flavors, adding forced induction to the all-new 6.2L LT1 small-block V8 engine. However, only one powerplant will make the final cut for the production version. According to sources of our own, there’s a high probability that it’s going to be the turbocharged variant, replicating the setup seen in the current BMW M5 and M6 supercars." [Note that the preceding is a quote in today's www.gmauthority.com.]

Maybe this is useful info for the high performance C7 (whatever they will be called)?"

I love the rumor mill that comes from the publication

Makes sense. Just a little surprised they elude to the Z06 using the LS7. time will tell. Will be interesting.

Hmmm.....and what about all the stories/rumors of no 427 in the C7?

BLKTA

Not much different than the info Keeks posted here months ago and also what was posted in the LT1 thread on ls1tech as well.

michaelinmech

In my experience, too often Motor Trend's insider info must have been gleaned from a 'Salesman' at the dealership, who has an Uncle that spoke with a Guy, and that Guy's brother is in charge of gaskets at the engine plant . . . . or similiar

This is BS. LS7 is dead. New motor is a LT4.....If people want the facts they can see this thread

This is going to be a long wait

They juked us!

At the rate gas prices are going up, we should be lucky there's a V8 Vette . I even doubt there's room for both Vettes (Z06 and ZR1), but we'll see. Will also depend on GM's CAFE figures at the time.

JustinStrife

I'd laugh my tail off if GM brought back the 427 for one of the higher performance models coming out over the next several years. For all the people snapping up C6z's as they'd be the last of the 427's... I wouldn't put anything past GM at this point. I trust what they say as well as I trust a politician.

BeaZt

If that happened some folks would REALLY be pissed off.

User 2623

Yes indeed it will..... [slow sigh]

Presuming the block of the LT1 can support displacements that high, add the direct injection bits, and a high 500s 427 isn't out of the question. Whether or not they'll actually do it is another matter entirely.

And if it were me, I'd make the ZR1 motor either a 396 or a 409 just 'cause.

I'm likely going to end up with one of these performance models - whichever is naturally aspirated. Likely will purchase a used one 3-4 years old with 5k or fewer miles for about 33% off sticker. This is great for two reasons:
1) Get the performance car nearly the same price as base
2) I'm not yet comfortable with funding govt motors.

OJCrush08

Yes, a high 500's 427 is very possible, have a '10 Z06 making 625 h/p N/A emissions legal h/p in my garage.

jimmybobby

I wonder if they mean a year from now or a year once the C7s hit the showrooms. Don't they know we can't wait that long.

No one said LS7 per se, but rather a Gen V that happens to displace 427 cubic inches.

Technically it was phrased such that it could have meant "next year". If the C7 Z06 is a 2015 or 2016, saying the 427 was not going to be around wouldn't technically be a lie. Similar to how they say there won't be a high end 'Vette for 2014. There will be eventually though. If they mention LS7 it could be an even more coy statement, as a Gen V 427 wouldn't be an LS7.

A high output N/A Gen V wouldn't be an LS7. The LS7 is Gen IV and indeed will not continue production, but that doesn't preclude Gen V from also having a big cube N/A fire breather.


That said, it seems like the LT1 has been set up to have the higher output engines use boost, and GM now has the precedence with the LSA and LS9 engines. Just wanted to point out it's not necessarily inconsistent with what we've heard official from GM. I would love to see a big cube N/A engine in a Z06 track terror, but I'm thinking we'll get boosted engines, which are also cool.

This is the same publication that swore on the 5.5L engine that was going to power the C7. We all know how that turned out...

Um, the C7 is already a V4. The next step will be to make cyl deactivation a selectable on/off so that it can run in 4cyl all the time and raise the city mpg.
