[/QUOTE=AnimalSS]

And, for someone to suggest that my idea of top of the line is the one with the highest price tag is insulting. I'll bet I paid less for my SS than you paid for your Z28. And, no matter how many ways you can think of to argue to the contrary, the fact remains that the 4th gen SS did get a performance upgrade over the Z28, however slight it may have been. [/QUOTE]

I never said that your idea of top of the line is the one with the highest price tag, I said that to some people they consider the top of the line to be the one with the highest price tag. So theres no need to be insulted. As for price, I bought my car used from a dealer 2 1/2 yrs ago for $13,500 w/ 45k miles when they were asking $17,000. It means nothing to me if you paid less for your car. If it makes you feel better that you did, good for you. Does that mean you got a better car than I did for less money ? It doesn't matter what we paid for our cars, thats irrelevant. Besides a fully optioned out 4th gen Z28 cost less than a fully optioned out 4th gen SS, and so what? That was usually the case with the 1st and 2nd gens, while the Z was the better performer of the two.

It may sound like I'm against the idea of the SS being named top of the line, but believe me I'm not. And it may seem that I'm saying all of this because I own a Z28, but thats not true either. When I bought my car, I had the intentions of buying a Z28 because thats what I wanted. There was a black SS parked right next to mine with 2k miles less for practically the same price. But I chose the Z28 because I like the styling better than the SS. If the SS had more than just minor handling improvments over the Z28 from the factory, than guess what, I would have bought that black SS instead of the Z28. But being as how the main difference was styling, I was fine with my choice. And like I said before, if the SS is the best all around performing Camaro for the 5th gen, I'll own an SS. If its a Z28 , I'll own a Z28. The point I've been trying to make is that when people wanted a Camaro that stops the best, handles the best, accelerates the best, while being an all around fun car to drive thats useable for everyday use, the Camaro for them would have been a Z28. The thing that bothers me is how GM says that they want to go back to their roots with the Camaro, and bring back what it once stood for. And the only way that I can see that happening is if the Z becomes the better performer of the two. Thats why I'm saying all this, to show those that don't know the history behind the Camaro and its models. But lets face it, things are different today then they once were.

I think its sad how they brought back the "SS" name for marketing purposes with the Camaro from '96-02 by simply changing the exterior style and making it seem like it was far superior to the Z28. I honestly wish that they had done more to the 4th gen SS performance wise while the Camaro was still being produced, so that topics like this one wouldn't be an issue concerning the 5th gen, not only with the enthusiasts, but with GM themselves. At least that way they would have a reason to make the SS the all around better performer without abandoning the Z28 heritage. But if thats what they are trying to do with the 5th gen, and if its going to help them sell more, then I'm all for it. I'll support whatever GM does as long as it helps the Camaro name stay in production. The way I see it, is if the Camaro's absence since 2002 has already made the enthusiasts start to disagree about which model should be named "top of the line" before its even been built yet, then the blue oval camp is already starting to get the better of us before the Camaro has returned. Like I said before, whatever the top is named, (as long as its not berlinetta ) it better own anything Mustang related.

(Again, don't take this post the wrong way or as an attack towards you or others that disagree with me, b/c its not. Nor am I trying to insult anyone. I'm simply trying to speak up for the Z28 enthusiasts and owners that aren't happy watching a car with this much history being insulted and pushed aside just to become another "trim" level by people who don't even know what the Z28 stood for and did for the Camaro name . Whatever the top is named, no one is going to be right or wrong, b/c it will benefit GM and its enthusiasts as long as the Camaro stays)

It so happens I had an SS and a Z sitting on the lot and after alot of thought went with the Z cuz I was originally going to get an aftermarket SS hood and spoiler to save the few grand more upfront but later I decided to go the way of ultra Z cuz it is diff. It has nothing to do with envy.
No problem man, I honestly wasn't referring to you or anyone in particular. And, I'm not trying to start an argument with anyone. It's just the fact that I've seen countless threads where Z28 owners are trying to rationalize putting SS badges on their Camaros because they have already upgraded everything else on their Z's to what came on an SS. Or, they went beyond with there mods and surpassed the performance of an SS and because they liked the SS hood and spoiler better, they feel justified in wanting to put SS badges on their Z. And, those people are free to do that if they choose to. It doesn't diminish my car in any way, what do I care? I just don't understand why more people aren't happy/proud of what they have and want to pretend it's something else. I'm sure if the 5th gen Z28s were somehow distinctively different (design-wise) from the 5th gen V6s but, V6 owners could buy those parts (intake, exhaust, sway bars, wheels, hood, spoiler, etc.) to make there car like a Z28… those 5th gen Z28 owners would not be happy. Do you think the "Dick Harrell" owners would be happy if we could all buy the body panels to make our Camaros look like a DH? I think a DH Camaro looks freakin' sweet as hell and even better than an SS, but I wouldn't turn mine into one even if someone gave me the panels to do so. Because, my Camaro is an SS. This is what I mean by "badge envy". We all modify our cars. So, which one comes from the factory with the "most performance" is really irrelevant. When it comes to performance, we're all going to modify our cars to the level we personally want. So why not buy the car you like the most and modify that? Everybody's saying that an SS is just a flashier model. So what? Obviously many Z28 owners who are arguing this point like the "flashier" looking hood, spoiler, etc. better than what they have. So, why don't you just get one in the first place? And, I know what your going to say, "it's cheaper to buy a Z28 then buy the parts and add them yourself." That's only if you don't know how to wheel and deal or don't have an option to purchase one or the other.

I just think this is a bogus argument. I don't know why these people who do this can't admit that they liked the SS better. And, once again, I'm not referring to those who put aftermarket hoods (sunoco, ultra-z, etc.) and spoilers and such on the Camaros. Just the ones who are making SS "clones". Just buy an SS if that's what you want.

But, back to the original question of this thread. I don't think the SS moniker has been dimished lately. And, I still believe that the SS badge will be put on the "top of the line" version of the 5th gen Camaro. But, whatever badge is on the "top dog" 5th gen is the one I'll be in line to purchase.

This has got to be the most supportive statement in this thread!!!

I agree with the marketing antics .....they are using "SS" to sell cars and survive in a competitive compact car market.

I personally chose my 35th SS for a number of reasons....appearance being some of them.....and IF they do decide to go with Z28...I agree that would be the best thing to re-introduce the Camaro vs. the Shelby etc..

We really can't lose.....has anyone thought that maybe since GM is back as the sponsor of the Crown Royal International Race of Champions...that maybe we ....just might....see a return of the IROC-Z????

I still have my IROC and they sold like hotcakes in the 80's......

Whatever they decide...I am just glad it's coming back.......I have to start saving$$$$$

Just like the other models, it gave people the option of whether or not they wanted a/c etc. You were still able to buy a Z28 fully optioned out with "luxury options" making it one of the most expensive Camaros you could buy while still being able to do what it does best, perform the best, which also made it a joy to drive.
Actually A/C wasn't available for the Z28 nor any other solid lifter car.

As far as driving pleasure, it wasn't that great on the street. Remember, this car had no guts under 3500. It did enjoy options that weren't available on the SS though. Namely 15" wheels and the available JL8 brakes(4 wheel discs).

The Z28 RPO code specifically lists it as a Special Performance Package. It was definitely a better handling car than that of the SS. Stopped just as well as the SS or better if you ponied up the money for the rear discs, but that was very rare. It was faster than the small block SS and the 325HP 396. About even with the 350HP 396. But was easily slower in performance than the 375HP 396. And much slower than any rare 427 equipped Camaro.

Look up any performance data from the era. Facts are facts but it seems time has a way of distorting what people want to believe as fact.

In the 1st gens, the Z28 out handled and was quicker than the SS 396 Camaro. That 302 was underrated, and could rev like a ****. It was also a much lighter engine and vehicle than the SS. The SS Camaros were the luxury cruisers with bigger engine options, the Z28 was all business. No automatic Z28s, no A/C, etc...

I'd love to see the Z28 be the equivalent to the Z06 in terms of rank within respective models.

Z28 = hardtop only, manual tranny only, beefier swaybars, bigger brakes, tranny/psteering cooler. Basically the "Z06" of the Camaro.
not to kiss the admin's *** but he's got it. a 302 z28 could blow the doors of a big block outta the hole. I believe the 302 revved to like 8 grand. one of my dads friends had a 67 z28 rs, and his buddy's 426 cuda couldnt overtake him until the last 50-100 yards of the quarter. another guy i know raced with a 68 SS camaro with a DZ 302 swapped into it. he had a powerglide mated to it with a 2400 stall and he said there wasnt much that could touch it. the z28 is the top race car and the SS is the big engined, optioned out cruiser. z28 should be king

I should of been more specific with the a/c comment I made but its an honest mistake when I typed as much as I did. As I mentioned, I wasn't just referring to the 1st gens, but also the 2nd gens. Solid valve lifters were replaced by hydraulic lifters in the 1973 Z28, permitting air conditioning to be combined with the Z28 for the first time in the Camaro's history.

When it comes to driving pleasure, thats mainly decided by the owner and what they considered as "pleasurable" to drive. FWIW, the Z28 was known as being "The most all around fun Camaro to drive" according to Camaro historians and their owners, in books, magazine articles, videos, and documentaries.

As for it having "no guts under 3500", I'm assuming your talking about the 1st gen, if so thats a respectable comment. Especially as how the car was meant to rev high. It might not of felt as powerful as the big blocks under 3500, but by no means was it a slouch under 3500 either. As I said in an earlier post, the 302s bore and stroke of 4.00 inches and 3.00 inches mean't this little engine would be a screamer.

When it came to stopping, when equipped with the $100 option of 4 wheel disc brakes, it gave the Z28 braking performance equal to the Corvette.


When it came to speed and the Z28s "little" 302 :

1967 Chevrolet Camaro Z/28
302 Cubic Inch Engine
- Bore : 4.00 inches
- Stroke : 3.00 inches
- TRW 11-to-1 pistons
- Forged Rods
- .485-lift solid camshaft
- Holley 780 Carb
- Aluminum Intake Manifold
- 2.02 Heads

The advertised HP was 290 @ 5800rpm. But it wasn't unusual for the Z28 to dyno between 360-400hp stock. By the time you put headers on, open exhaust and the over the counter camshaft, it would actually make 450-460hp.

The Z28 was never meant to be a drag car, but it just happened to be a decent performer at the strip also. It 1968, a Z28 won the NHRA Super Stock Championship in a final race between, you guessed it, two Z28s.
It was faster than both the 325hp and 350 hp 396 SS in the 1/4. And when it came to the 375 hp 396 it was within 2 tenths give or take making it a drivers race. But since the Z28 was made all its power in the upper rpms, was lighter, and was making very similar power stock for stock with the 375 hp 396, it would pull on the SS in the top end. I already covered the rare Camaros such as the Yenkos, and ZR1s etc but those were in a different league than both the Z28 and SS and shouldn't be compared. I don't have to look up any performance data from that era, like I said, I have seen the proof in both books and video documentaries.

In the case of the Z28, time has nothing to do with distorting what I believe, b/c it has nothing to do with what I believe or what anyone else believes. It has to do with knowing the difference between what is fact and what isn't. And you can't argue with history and what the Z28 accomplished as both what it was and wasn't designed to do.

This has become both boring and repetitive having to explain myself over and over again. I can see that no one is going to change their mind or even want to try to understand what I'm saying. It seems that everyone is out to try to prove the other guy wrong regardless of what the facts are, and thats not my intentions. With that said, take what I wrote throughout this thread however you'd like to (for anyone that read it) because I'm done.

There needs to be a little more reality like the above added back to this thread. The z/28 was not the ultra-master of acceleration over the SS 396, like some here are saying. Occasionally, if the wind was just right, it might go a tick faster than an SS (mostly due to sh*t tires not being able to plant the TQ of the 396). But the Z was a dog down low.

And if the cars were modded, forget about it. 100 cubic inches is going to have more potential.

The z/28 had a great engine... for a 302. If you think a 302 is going to be "top dog" over a 396/402, then please come back down to planet earth.

Give the z/28 props for what it was: a homologated trans am racer with superior braking, handling, and with a very nice small block. No need to distort it into being the 1/4 mile king.

I was able to find out this info on the Z28 and SS...

(Z-28) 302/290bhp: 0-60 in 6.9 sec, 1/4 mile in 14.85 sec @ 101mph.
(SS350) 350/295: 1/4 mile in 15.4 seconds @ 90 mph.
(SS396) 396/325bhp: 0-60 in 6.0 sec, 1/4 mile in 14.5 sec @ 99mph.

I found this info out for each pony car back in the day and each engine options they had for each one (8 cylinders only). I thought we could compare the Camaro to the other pony cars and see how the Z/28 fared against each. Let's take a look at each pony car and what it had back in the day (there were 2 pony cars for each car company)...

After reading all 6 pages (whipes head), Im ready to state a few things in this thread.

One:

The yenko/copos were not SSs, they were stripped Zs and had no badging.
No, COPO's were not stripped down Z's, but base model, stripped I6 Camaros with a BBC 427, the suspension, and a cowl induction hood.

Two:

A few people have mentioned that the 302 was underrated, and that is 100% correct statement, but no one has mentioned that the 396 was underrated too. Without mufflers, made about 500-550hp at the flywheel. Blue printed was about 550-600hp.

Three:

I don't get why most of you are saying that the 302 is the best performing Camaro of the first gens, thats not 100% correct. The Z28 was a road race king, took it home each time out of all Camaros. When you got to drag racing, the 396ci 375hp was king, remember that you could get the SS without all the fancy options like AC as well. The aluminium block was an entire different story, weighed as much as a sbc with bbc power.

My dad was lucky enough to purchase a 1969 Z11 Camaro SS/RS 396 Automatic NEW back in 1969. This car is 1 of 7 cars with Aluminium heads, and this car has *****. I have had the privilidge of riding in the car, learning the history of the car, and hearing stories about what the car has done. With 6k origional miles on the car, she is still a baby.

Well, I thought I would make another feeble attempt to direct this thread back to it's original question.

Even though this thread has prompted a debate over what "top of the line" really means, I think we all know that it means "the highest level of options and power available." The degree of how much higher is irrelevant to this debate. And, as you can see by the data that 00 SLVR Z posted, regardless of track times (we all know the Z28 was lighter), my point that the SS was the "top of the line" model is validated.

(Z-28) 302/290bhp: 0-60 in 6.9 sec, 1/4 mile in 14.85 sec @ 101mph.
(SS350) 350/295: 1/4 mile in 15.4 seconds @ 90 mph.
(SS396) 396/325bhp: 0-60 in 6.0 sec, 1/4 mile in 14.5 sec @ 99mph.

… and what would the 396 make with the same add-ons, hmmm? Obviously, (or maybe not so obviously) we're not talking about what these cars could've done, we're talking about how they came from the factory. And, one more time for the cheap seats, the SS came with the bigger engine and more options. The Top of the Line.

This maybe a case of the pot calling the kettle black.



Quick Reply: Top of the line named Z28 instead of SS
