Z/28 might not be much faster than SS

[309grovest]

If and when GM builds the Z/28 I do not think it would be much faster than the SS if they use the LS-A but it will probably handle much better - that will be GM's goal with the Z/28 - In my opinion.

If you use the LS-A you will add about 150 lbs to the cars weight b/c the LS-A is that much heavier than the LS3. The added weight is due to the s'charger and related hardware. Also if you upgrade the suspension, go to bigger brakes, wheels and tires you will add even more weight -the car's weight could approach 4200 lbs. This is the weight of the CTS-V and even though GM says the 0 to 60 time of the V is 3.9 I have never seen a test where it achieved this time - usually the time is around 4.4 secs to 60.

Therfore if the Z is approx. the same weight as the CTS-V and they both have the same engine I would think that they would post similar acceleration times- unless GM lowers the gearing in the Z. I believe the SS does 0-60 in about 4.6 / 4.7 - so if the Z accomplishes 0-60 in 4.4 or 4.3 there is very little difference between the 2 vehicles. If you have an SS and spend 5k on engine upgrades you can get the 0-60 time down to 4.0 or the low 4's

For less money you have a faster car, but going back to my original comment the Z will handle better - which was the goal of the Z when it was originally introduced.

The Caddy weighs 4,250 lbs. The LSA weight difference to the LS3 is less than 50 lbs. Not that any of the rags matter but C/D got down to a 4.0 with the automatic. Weight would be the enemy there. Motor Trend got a 12.3 in the 1/4. Half a second is huge and the amount of power to get that .5 second is significant. So you are right it's not like your SS versus a dump truck but in the performance car world a .5 second is huge. That being said you can spend 10 grand and get the same performance for less money but you do not have the warranty. I agree with you that part of the appeal of the Z will and should be handling.

My opinoin is a SS with a supercharger will probably outrun the Z/28. the Z's advantage will be upgraded suspension,brakes WARRENTY.

now why do you have to be such a mood kill, but i guess well just have to wait n see

I am thinking a tt v6 with stunning suspension upgrades ala leno. Remember the first ever z was a 302 and the SS was a 350.

AND 396!

True enough.. Almost forgot about the 396 pretty rare.

Not really that rare. Production numbers for '67-'69 model years: 396/325HP 18,528, 396/350HP 4,587, 396/375HP 11,185, so over 34,000 396 Camaros were produced in those three years (compared to just over 28,000 Z/28s in the same three years).

Supercharged Z-28 will definitely be much faster.

As much as I would like to see a 2012 Z28. It might be to GM's best interest to build a 550+ HP, (S Borla exhaust, better hood, ext....) and keep the SS name. When the lighter frame comes out 2014 or so then start production on a Z28. Thoughts??

I disagree, I think Chevy needs a new Z/28 sooner rather than later. The advantage to a sixth gen. Z/28 would be the possibility of keeping closer to it's heritage (an idea I really like), but I think that time frame is too long to not have a Z/28 in the lineup.

Why worry about the LSA? GM needs to get off their butt and get us a DOHC V8. At that point the performance numbers can be off the chart. Ford is getting comparable power plants with smaller engines because of this. I would gladly exchange a pushrod 6.2L for a smaller 5.7L, or a 5.0 like original Z28, DOHC because you can get more power. Design one, market it in the Z28, and see if ford can keep up. They went back to the drawing board for their 5.0 and only pumped a rated 412, prolly more but they are being sneaky.

huh. . .a double over head cam engine weights more then a push rod, makes less tq and has to spin up higher to get the same power. . .

also from what I've read about the new 5.0 they have done a lot of tricks to it to get that 412 hp. some tricks that are used by the aftermarket normally. so now you are getting a car that the engine is getting on the edge of being tapped out with basic addons (exhaust and intake)... so tell me why I want to start out with an engine I already have to do more expensive work to to make faster?

give me the old antiquated push rod motor. weights less and makes its power down low. . .right where you need it leaving the starting line. . .and then makes it all the way up to red line. . .

No, they absolutely do not...The LS3 is a comparable, if not better engine than even Ford's brand new little 5.0 liter motor. And it's based on early 2000s tech! (hrm, hrm..."imo")

GM is beginning to produce (or fit plants to produce) the new generation of Chevy Small Blocks. Next year, look for the first to arrive....in a VERY big way.

And yes...all sources indicate they will still be cam-in-block.
