We already know that unlike LS3, LS7 is one of the engines offered for 2014 models from the leaked 2014 GM VIN decoding table. Now there is this from LT1 discussion in LS1Tech:

High output? Does it mean that we'll have an updated version of LS7? That sounds delicious to me

JBauer47

Everything I have read has lead me to believe that the LS7 was "maxed out" as far as its potential was concerned. That it was pushing the limits of reliability and there wasn't a whole lot of room to play with. And there is supposedly a HO version coming out ? What am I missing ?

In a previous post this guy claimed a high output LS7 was canned if they couldn't get something on the Gen V working right.

And didn't GM say they were not doing any more work on Gen IV?

I've always been very skeptical of this guy's claims as a GM rep and story.

I am not even wondering if LS7 will be offered in a car, we already know that for almost certain. Check out the leaked documents (which were hosted by a GM site initially, so they're not hoax) below:

GM said Gen IV would not be offered in C7, but never said anything about other cars like Camaro or upcoming SS. Anyhow, what grabs my attention is the "High output" adjective: will it be revised by any means? Perhaps a different head?

I'm familiar with the leaked VIN docs, which is indeed very interesting. Very interested in seeing what GM comes out with.

However, my comments were specific towards development of an High Output LS7. I recall reading during the Gen V news that GM was no longer putting any more development or efforts into Gen IV motors and moving forward with just Gen V stuff (makes sense). I guess my point is... if that is true, then how they are working on an High Output LS7? Wouldn't that be continued efforts on Gen IV? A Gen V variant would not be the same as an LS7.

2nd point is, many posts earlier in his thread (I stopped following once I realized he is probably just trolling), he mentions GM had the H.O. LS7 idea as a Plan B to the Gen V if that wasn't ready yet, and the idea was scratched. Since Gen V is a reality and the H.O LS7 was canned, why is it on the table again now? What is the truth?

I just don't believe his claims or story, so I take everything this guy says with a grain of salt.

Tadge J stated that the LS7 was over when C6 dies.

If there is a H.O. LS7 I hope what ever is updated is easily applied to exisitng LS7s.

Exactly why the word "high output" is so exciting! Perhaps they only mean the regular LS7, which is already high output; we will see.

A lot of the comments about things being discontinued and canned could be in reference to their use in a C6 or C7. It's easy to say work on the Gen IV is over...for Corvette models. Isn't the LS3 in a Camaro? Won't they still have to offer that engine for a new MY? I'm excited to hear this information. I hope whatever they do to the HO LS7 is retrofittable to our cars.

Ozer stop telling us about what you dreamt last night.There is no rumor at all about the ls7 remaining as part of the engine choices for 2014.None whatsoever!What is it with this need people have of fabricating there own stories.When the truth comes out it only makes you look like a dummy.I guess some people are just attention starved there is no other logical explanation.

Check out what 'E' stands for from the engine type table for 2014(!) GM VIN decoder. You should do the due diligence and check the provided references before calling someone dummy, or you risk looking like a dummy yourself :-)

Interesting to see how they will use the LS7 in the Camaro. Very few in the COPO's last year. Maybe 1LE? I'd love to see the LS7 live on in Camaro.

I remember reading earlier this year that GM trademarked the Z28 nameplate.. there was some speculation of a twin-turbo V6..or something light weight...but the LS7 would fit nicely in a track package camaro! and my bets is there is plenty of LS7s left over from a dismal 2013 Z06 Corvette model year

Jawnathin

This was during the Gen V reveal, so perhaps specific to the Corvette, but I thought it was specific to Gen IV in general.

Re: LS3 in Camaro. Yes, it appears to be available in 2014 MY, but the statement was 'no further development', which I took as, no more revisions or efforts for a Gen IV platform motor, not that they wouldn't continue to keep them as is in the cars they sold them with.

Ls7 with updated heads and cam direct injected would make well over 650 hp ...

An HO LS7 in a Camaro, this makes no sense. Chevrolet has never put a higher HP version of any engine in a Camaro. The Corvette has always been the flagship. The LT1 Corvette in 1992 was higher HP than the 1993 Camaro, the LS1 same thing and now, there are 2 supercharged motors besides the ZR1; CTSV and ZL1 and they are both lower HP. No, if there is a high HP anything, it is going to be in the 'vette, before the Camaro, IMO.

X25

What you're saying makes sense, but it was also announced that there would be no new Corvette variants using LSx engines. Just a thought: if not Camaro, perhaps a special SS might come with it then? Or a special Camaro before gen 5 Camaro retires?

We still don't know which car would have it, or if it will be the same LS7 or an updated version. Since GM renames engines for any major update, I honestly doubt that it would be any different...

Too-Fast

Could be, but I just don't see it, they would be breaking a tradition that goes all the way back to its inception.

Tadge probably made that statement because at that time it may have been true. It also helped push out some 2013 inventory to those that had to have the LS7. However the marketing guys run the company and they saw some nice advantages to keeping this engine alive. I have a feeling the C7 Z06 will have something called an LS7A which will be a high output version of the LS7.

Oh, the LS7 is going in the last year of the 5th gen Camaro OK! Count on it. The ZL1 Convertible has moreHP than any Vette convertible, so throw out anything that happened in the past.

The 427 Vette has been a huge success and GM has picked up on it. It will be a going away present for all the loyal followers.
