What's going to replace the LS7?

I guess this should really be in the Other Cars section, or a Corvette section, but it just struck me - If the LS7 is going to be phased out by the time the Camaro hits the market, then what's going to replace it? Not in street trim, but I mean the racing program. I really doubt it will be a supercharged LS3, since it is, well, supercharged. They need to come up with something naturally aspirated, high power, and high revving. And being an LS engine, it'll fit in the engine bay of a Camaro...

LS9 and LSA have been used interchangeably from all the hint posts I've read, essentially until we have a confirmation its best to assume either or both is the LS3 supercharged.

Replacement is probably whatever the next gen vette is getting (blue devil,stringray, ss, whatever you want to call it) and I highly doubt it will go in the camaro.

whats an LSA?



and the camaro will eventually get whatever engine goes in the vette. always has. which is why the camaro is always better than the mustang. we get the vette motor!

since the LS 7 is for the most part hand built, it might stick around a little longer? LS8.. or 9 maybe?

There's nothing that says The top Vette engine HAS to be hand-built, or HAS to be N/A, it's just sort of been a trend. Of everything I've read, the Super-Vette is supposed to get a supercharged LS3, which is strengthened (rods, crank, pistons, valves etc.) for High-power, high-speed use. Hence the Completely different engine RPO, LS9. So that engine could replace the LS7, and make it into the Z06. But who knows what GM has up there sleeves They hava knack for surprising us with things like this.

I wouldn't doubt that there will be an LS8, not becuase it follows "7", but because it's one of the few LS(single digits) that hasn't been used yet.
LS5, LS8, LS0....I don't think there will be an LS0, it doesn't sound right. So maybe they'll start using Letters, LSa,

Like I said, who knows? but I think we can look for the LS9(supercharged LS3) to replace the LS7.

LS9 would be supercharged. That'll work for the street Vette, but I doubt it for the racing version. They have to put something into the race Vettes. Whether that trickles down into production cars or stays put in the engine bay of the C6Rs, I want one

Haha true true. I just want to see a high-revving engine option. If an LS3 will do it, I'll bore and stroke that out and work over the rest of the engine (cam, heads, etc). I would like it to still be making peak power in the mid 7k RPM range

Here is what I have heard/read but dont know for a fact:

LS9 supercharged intercooled 6.2L ~650 HP LS7 replacement, most likely Corvette Z0(6/7??) only.

LS8 supercharged non-intercooled 6.2L (detuned LS9) ~ 550HP, can find its way into other models.

I was reading an article about the new "Super Corvette" (that is yet to be named) and there was a lot of talk about a supercharged LS3... :eek:

Most all of the "Super Cars" have some kind of Forced induction, whether it be Superchargers, or Turbos. I can easily see it happening.

In fact, I look forward to seeing it happen

Okay...for those of you who have read that other thread about the GM video blogs, it was not a GM rep, but it has been stated that the LSX is a whole engine, not just a block. Again not solid info, but damn near as good as any. I apologise to all those who I "shot-down" regarding that. I'm no engineer, so... woops

This thing is said to push out 640hp:eek: N/A!!...and unless I heard the video wrong, that's Carbeurated. If the inject this thing...could we expect more? Because my opinions change so rapidly , I think THIS will be in that "super-vette"...and perhaps the Supercharged LS3 (LS9) will take over for the LS7?

They've also said that there will be a 9 liter monster in there...However, in a side-remark by GM official, I'll get the link later, they said that the displacement of the engine in it will be "significantly larger than the LS7"...:eek:

I promise I'll get a link soon.

EDIT: http://www.autoblog.com/2007/04/13/2...age-of-tuning/

okay, so my quoting is a little off.

I think it will still be a few years before we see that one. they said that the C6 series shouldent end till 2010/2011. and that stingray/blue devil vette would be for the last year of the C6 corvette.

not really pertaning to the conversation, but my dad's friend gets a new vette like every time a new model comes out, for example, he had a silver c6 a few years ago, then traded it for a 07 zo6, and he has already ordered or whatever the blue devil, and he's gonna trade his zo6 in for it, and he's owned the z06 for just over a year, I call that a covette enthusiast, he's worked it out with his wife so he can get a new vettte every year, rich !@$#@!%
