Claims that HSV will use the LS7 because Lutz also wants it for Camaro. Due to packaging problems, claims are it will be a wet sump installation which makes it relatively easy to install the LS7 on the regular production line.

No LS7

 

whats in a name?

 

What would it require to transition to making a mass produced small block at 7L with wet sump oiling based on the LS7?

 

That's what I thought, but that is the most recent post I've read re LS7. Have GM had a change of heart? IMO, unlikely as the LS7 would still be more expensive than a blown 6.2L, not to mention, less powerful.

 

I still think a 427 N/A Camaro is music to my ears. Plus, it also gives the Vette a bit more "room" to be the top-dog in hp.

I think it will come down to cost though. Which is cheaper to manufacture: a 7L LS derivative, or a 6.2 blown LS derivative? With many other GM cars looking like they will get the 6.2 F/I motor, it might mean that would be cheaper to produce in the long run and would probably make the most sense from a production standpoint.

 

I'm holding out for the blue devil turbo version myself...

 

For me there is something intrinsically special about having a 7L engine that was race bred. Competing at LeMans and winning its class...

I doubt that GM would race the blown 6.2. How many supercharged engines are raced? I don't know of any!

 

Are you guys clinically insane?!?!?

How is a supercharged engine CHEAPER than a NON-supercharged engine?????????

For a minute, let's come off the Z06-LS7 "cloud", and think of a mass-produced "LS7". I have said this for a LONG TIME on this board (and finally, something pseudo-official has been rumoured! ) ..... build the "LS7" without the dry-sump system, and build it on the PRODUCTION LINE with the REST of the LS(3?) fleet. It does NOT have to be "hand assembled" like the high-class Z06. That is something done as a "premium/status" feature.

Here's a question: is the supercharged 6.2L rumoured to go into the Camaro going to be hand-built? Or will it be mass produced like all the of other Gen-III/IV engines??

SO, can someone please tell me what will COST SO MUCH to build a 7.0L N/A V8???

A 427 c.i. V8 in a Camaro is just so right!!!! Do it!!!!

 

all the strenthened parts in the rotating assembly, closer and more accurate tolerances...I don't build them, so I couldn't say specifically...but even if you mass produced them, I'd have to believe they'd still be expensive.

AND the point of a hand-built LS7, IMO, is to have a hand built LS7. It wouldn't be the same otherwise.

That's not to say I wouldn't want one anyways

A) "hand-built" is a great premium to pay if you're paying for a Z06. But to be honest? There are a thousands and thousands of LS1's & LS2's out there under the hoods of C5's, F-bodies, and GTO's. There have been very few detrimental failures that I'm aware of that have been as a direct result of assembly failures, or less accurate tolerances . YES, the early LS1's had oil consumption issues, but those got addressed, and there have been VERY FEW issues with ANY of the Gen-III/IV engines (INCLUDING 4.8, 5.3, & 6.0L truck engines, which there are certainly hundreds of thousands of as well!! ).

B) if GM is putting out a supercharged 6.2L, don't you think the "tolerances" need to be pretty darn perfect?? Won't that blower put a bunch of extra load on the pistons, rods, crank, etc?? But you're ok with it being mass-produced on the assembly line??

My point is: build a 7.0L / 427 c.i. / "LS7"-esque derivative engine. I'm not saying "The LS7", but the same motor minus dry-sump, no hand assembly, etc.

Cheap. Big. HP.

 

Regardless of all the parts, and whatnot...I still stand by what I said about being handbuilt for a reason. I really don't think the LS7...or any 427 is meant to be used across a broader scale than only the Corvette. At least not today...

btw, everything I'm saying is arguing that it probabaly won't happen...not that it can't

And in this 'friendly' conversation, has it been established whether or not we're talking about the LS7 in an "everyday" Camaro, equivilant to the 4th-gen Z28 and S models? or a super-'maro, designed to completely face-plant the GT-500?

 

A production line built 7.0L engine isn't going to have the same quality and durability as the handbuilt version. So to play it safe, GM would certainly dial back its performance to increase its longevity.

Hense one reason why they are moving to a 6.2L supercharged engine to achieve similar performance.

 

... in bold ... B.S.

Not to knock the guys who build the LS7's, but you will never convince me that the production-line engines are any less "durable" than the hand built ones. Durability depends primarily on the PARTS installed, and again, you'll never convince me there's a problem with the ASSEMBLY of those parts, based on the successful history of these engines over the years.

SO, what are we left with?? Your arguments are crap!

Fine, to "play it safe", dial down the 427 to ~475 HP instead of ~505 HP. But let's be honest, 505 HP is NOT the maximum potential of the LS7 . That's a nice "easy" number for the engine to achieve, and still be EASILY covered under warranty, and meet emissions standards, etc. "Hand-built" and "dry sump" have NO effect on emissions, and I highly doubt any warranty issues would suddenly ramp up because it's not hand-built .

WRT the question about "what car does this engine go in"?? Why, the everyday, regular production (not "super uber" Camaro) Z/28 .

 

okay...so maybe a 7.0L is possible...but not the LS7. Do I seriously think we'll see a 427 in an everyday Camaro...no, but I can dream with all of you...
