But I doubt that GM is gunna offer the LS7 to the Z28 (if theres really one coming) because it gunna make the cost of the car go up with the track ready suspenion.

I think GM is gunna put a Dry sump 450hp LS3 and track ready suspension in the Z28 to keep the cost in between the SS and ZL1.

But a High Revving engine would be a much better choice.

Don't detune the LS7! Nobody who wants a Z/28 wants anything less than the best.

On GM Performance Parts there is the LS376/480, which is basically a cammed LS3 and it produces 480 hp/475 lb-ft of torque and comes with a 2 year warranty. I want the best LS3 rather than an LS7 that is not as good as it should be. Imagine the idle if that engine came stock...and look at that torque curve!!!

And just to compare the two (hp) approximate:

RPM - LS376/480 vs. LS7

2000 - 100 vs 120
3000 - 240 vs 225
4000 - 370 vs. 320
5000 - 450 vs. 430
6000 - 480 vs. 500

Average - 328 vs. 319

Of course if they don't detune the LS7 its the engine I would want...but what are the chances of that?

How about a more balanced car one designed for road track. Small Engine (v8) standard shift only, but balanced for road track heavier sways and springs, lighter wheels, cts-v brakes.

$5,000 for 55 HP? No thanks.

But even worse the difference between the 2 crate prices is more that $7,000 not $5,000.

So if you figure in the 480 hp LS3 version, The difference is still more than $7,000.

So $7,000 for 25 HP. Any takers? The LS7 does not make sense in the Camaro.

And the LS3 and LS376/480 are within a few hundred of the same price for a 50hp gain. If the Z/28 starts around $40g, then that leaves about 5 or more thousand in the price tag for further upgrades such as suspension part upgrades, tire upgrades. Not to mention the LS376 has more horsepower available under 6000 rpm than the LS7. That's not to say 1-2k can't be spent to allow the LS376 to rev a little higher...maybe 7000 or 7500 rpm? This theory...it is crazy - but is it crazy enough?

Folks, a 7.0 Liter V8 with 505/470 specs HAS AN RPO CODE...LS7

A "hot-cammed" 376/480 DOESN'T...

You don't just snap your finger and install an LS3+ in an automobile and call it a day. DEVELOPMENT/CERTIFICATION/VALIDATION...CO$T$...

Now, take those co$t$ and add 'em to the crate engine costs...and, built in low volumes AS CERIFIED/VALIDATED, your piece-cost will rise...closer to the existing LS7 price...no?

Ergo, NOT $7,000 difference, but approx. $5,000...

If this "not-for-highway-use" LS3+ was "such a great deal", then why isn't it already in a Corvette...or Camaro?

Btw, the LS6 readlines at 7k just like the LS7 does so thats nothing new. I vote for the Z06 LS7. i would take that all day long. A cam and headers in a Z06 makes 550rwhp.

Is it just the Z28 section, or do too many people just jump in without reading any thread before they answer?

It's not just the Z/28 thread, it's all threads in the forum. That's why there's so many multiple same answers and picture posts.

Unbelievable!
Their comments I fear reverse the positive flow of some threads that are hoping to sway the thinking of those in high places.

durability testing? does it matter? it's not like they can't and will not. it's a mythical car. we can dream.



my personal pref. would be if the ls7 is used that it be a dry sump system. I do love those curves. but I'm still holding hope that the next gen engines are coming out and they slide one right into a z28, a great all around car.
