Please read the latest issue of Road&Track for a great comparison the Vette, Ferrari, Audi and Aston Martin, specifically the side bar on p.65 and then the whole article. You should be impressed and enlightened.

OHC Engines are taller.....
One of the most important things to remember here (and this is often overlooked), is that engines with overhead camshafts are much taller (given roughly the same engine displacement). Often as much as six inches taller.
Bottom line....if you want a lower hood line, a pushrod engine fits the bill. The LS2 and LS3 are about as high-tech a design as you can get.
The form factor of the LS2 and LS3 is about as compact and low as you can get.
If you want a comparison, just take a look at the BMW Z4 straight six, it is one tall mother. Note the hood line. Same with their V8's.

I apologize for my earlier post, I've been taking a lot of **** since I bought this vehicle and I thought you were just trolling the board looking to start trouble.

I sighted the civic due to a person at my job who drives a turbo SI that (according to him) can totally kick my Vette's *** and apparently looks better to.

Welcome newbie. I have been here since 2004 and have been driving vettes since 1969 and I still do not know anything techincal. All's I know is that I love the vette and the small block chevy engine has been the envy of many people. Do not think you would be making a mistake if you went for the vette.

Thanks
Thanks again for all the replies. I am seriously considering the Vette also, and I know I will love the car. I am facing the same **** at work also with ppl saying the Vette is old engine style which of course I don't agree with. I actually also read the article about comparing the Vette (std C6) with the Ferrari F430, Aston Martin and Audi R8. I am very impressed with the Vette.

The OHV vs OHC deal isn't really old vs new technology, it's just that alot of perceived "modern and sophisticated" cars have DOHC engines. That, in and of itself, doesn't make the technology better. They are just 2 ways to open and close valves. One is simpler to design, build, fix, has fewer parts, and is generally cheaper to build, and the other is not. It's up to you to decide which one is really "better". I've had examples of both, and both are fine, but for big cube musclecar engines, the pushrod is king.

Thanks for the link, it is a great reference.
I am still waiting for the right time due to financial reason, can't wait to get the Victory Red. Hopefully within 3 months. I also have dropped an email to the forum dealers, their 08 coupe still about couple thousands above what I hope for.
BTW, is the Z51 option something that worth to purchase if I will never track my Vette?

in a nutshell. Pushrod engines have the cam down low and use pushrods to open and close the valves(2per cylinder). Modern engines have overhead cams(up high)and have no pushrods. Pushrod engines have 2 valves per cylinder,while overhead cams can have as many as 4 valves per cylinder...meaning better breathing,less fuel. .....in a nutshell.
Now it is true that double overhead cam engines are easily adapted to 4 valve per cylinder design, but they are limited to inline penta-roof chambers, which have poor squish characteristics. Pushrod engines can use hemispherical chambers with central ignition, or the Chevy wedge design which results in superior squish properties (this allows a higher compression ratio before detonation for a given octane gasoline, and hence more power from commercially available gasolines). Realize that the small block Chevy engine was the first mass production engine to surpass 1 hp per cubic inch of displacement, on ordinary gasoline, at modest RPMs (which translates to high torque and far superior engine longevity than provided by the whiny little screamer overhead cam European engines).

Actually, cam in block overhead valve pushrod design is more modern than overhead cam design. When David Dunbar Buick developed the modern cam in block overhead valve engine, it was a radical improvement over the older overhead cam engines then in current use. Cam in block allows a lower mass, lower complexity, lower engine profile, with a lower center of gravity, allowing a car to have a lower body line and better handling properties.

The Corvette team has put a lot or resources into the LSx engines. It seems to have paid off.

The 2000 Si had roughly 150 hp, the 06 and above stock doesn't even break 200 hp. I'm not sure what the turbo is adding but I highly doubt he'd take your Vette. Never know though, some of these tuned and modified ricers are notoriously quick.

IF someone allready said this... then let me say it again...
IF AIN'T BROKE.. DON'T FIX IT....
PS...I have the state of the art engine...The LS3 is a MONSTER BARGAIN
