ZL1-LSA-MR+LS7+Pedders Coilovers = Z28?

If they went that route then it would be safe to bet we may not see a Z/28 until the 6th Gen Camaro is released.

Now if we cant have the LS7 in the 5th Gen because of cost and the fact that it's on its way out.... And we(they) dont want to wait until the 6th gen to release a Z/28.... What are our other options to create a 5th Gen Z/28????

It has suddenly become clear, here, in the last few days the Laguna Seca is being used as the "benchmark" for performance by many. A $6995 option package which saves ZERO weight (rear seat delete = chassis bracing), and is being sold at a rate of 15% of BOSS production. A "halo" for a "halo".

Would GM consider the same?

LS3+ "Z/28" as "Base" @ $40ish (as per RJ), and an LS7 @ a $6995 premium, for a "Halo" of a "Halo"?!

Keep in mind, Mustang's current version has a "Best Before" date roughly equal to the Gen-5 Camaro...

The other thing with the LS7 being on the way out is ... how do we know that it will be cancelled before the end of the gen IV run? If its not, then its going to live roughly as long as the LS3. And its more work to get a high output version of the LS3 into the Camaro than it would be to just use the LS7.

That, and the fact that mods to the LS3 CO$T...shrinking the "cost to GM" differential between the hot LS3 and a production-ready LS7.

You cannot simply say "an LS7 is TWICE the cost of an LS3"...TWICE of WHAT?!

If the Vette's model change arrives in 2013 as a 2014 thats only two years a way. If the new vette does not use the LS7 and only uses GenV engines the LS7 will be dead. With that being said do yall think GM could recoup the R@D and validation cost of trying to drop a LS7 into the Camaro in only 2 years?

Yes I know we are dealing with a lot of if's and but's here but its all we got

That is a #3 loaded question. If they were to use data from the LSA ZL1 for driveline validation to reduce the cost my guess would be yes. If they start with a clean sheet of paper my guess would be no.

Gee, Pete, why wouldn't they?! This IS, after all, the New GM...

With regard the LS7 usage in a "Z/28", I bet you a Tim Horton donut (your choice) MORE LS7s would be built for a sub-$50 Camaro than ever were used in north-of-$70 Vettes...

But to use the LSA ZL1 driveline validation that same drive line would have to be in the Z/28 correct?

[LOWDOWN]

Yes, as mentioned earlier, for durability and reliability (warrantee containment), piece-cost reduction and, therefore, improved profit$.

Win-Win-Win

Not a win when you figure using that heavily beefed up driveline is going to add weight to what we are trying to make a track star.

[LOWDOWN]

Again...starting with an LS-contented interior, your friend Number 3's careful use of seam-sealer/mastic/insulation/underlay etc. etc., dropping the dry-sump tank from the LS7, using forged wheels (19s??) and lighter non-run-flat tires will at least offset the HD Tremec/HD diff/bigger brakes/HD bars. The springs, as per Pete, if not MR, are a wash, as are the higher durometer bushings throughout...

An LS7 "Z/28" for the final Curb Weight of a 1SS...3849...or less...as per the power-to-weight calculations mentioned above.

[ShnOmac]

Again...... If the LS7 is really on its way out than none of this matters! That is why I am trying to look at all the options for a Z/28 (also GM's side).

[LOWDOWN]

Mac, would you agree that, regardless, a production-ready engine MUST be used in a Gen-5 ZEE?

If yes, your choices are few...LS3...LS7...LSA...LS9...at this time...and NO Gen-5 V8 for Camaro till after the Vette gets it, which is easily a year away, and then likely a year after that...

Durability vs weight. We can still pull 200 pounds out with smaller wheels and tires, titanium exhuast, less sound insulation and so on. AND, the extra weight is in the back half of the Z/28
