The newest LS engines are basically all new. They don't have anything in common with the older ones other than they are cam in block. The Corvette still gets some of the best mpg for the amount of horsepower it makes. I don't think a DOHC engine that makes the same horsepower would get much better mileage. There is still D-o-D, DI, VVT, 3 valves per cylinder out there.

I don't think anyone is claiming that DOHC is a poor design, heck it's been around longer than the pushrod! We just don't see the end of the pushrod just yet. GM hasn't yet added 3 valves per cylinder, VVT, or DI to the LS engine. There is still some life left to it.

IF, through some government mandate, there is a shortsighted restriction on engine displacement, then yes, I could see the Corvette being forced to move to a smaller displacement DOHC setup. But until such a restriction exists, there is no reason for the engine to change configuration. BTW, DOHC has been around in production cars since 1928. The Cam-In-Block pushrod configuration that we know today was released in 1949. So which car is using the older technology again? Porsche or Corvette?

Hey GM! Remember when you put the Camry and Accord next to the Aura and Malibu in showrooms? Time to bring that idea back.

You CANNOT fit a DOHC 8.3 liter into the space a pushrod 8.3 liter can fit in. FACT!

you're getting a warn for this one. I'm tired of it. Horsepower per liter is a RED HERRING!

You seriously have no clue what you're talking about. Do you know that the leaf spring in the Corvette is not what you're going to find on the back of your dad's 1983 F-150? It's a high tech, fiberglass, transverse leaf spring that gives the Corvette so much of it's handling advantage. A 5 liter DOHC with 400hp buys you.... what exactly? In the same packaging, you can get a 7 litre with 600hp. DOHC is a step backwards for the Corvette in overall performance.

Incorrect. In the 80's most import 4-cylinders on the economy end of the spectrum had SOHC not DOHC. GM actually mainstreamed the DOHC 4-cylinder before the imports with the Quad-4. Toyota offered their first DOHC V6 in 1989 putting 151hp at 5200rpm and 159ft/lbs of torque at 4600rpm. This was roughly equivalent to the typical GM 3.1 litre pushrod of the day putting out 140hp (can't find the rpm) and 180ft/lbs with great low end torque. Just two years later GM introduced the 3.4 litre DOHC V6es putting out 210hp @ 5200rpm and 215ft/lbs @4,000rpm. Toyota wouldn't release a V6 that exceeded this horsepower rating for over 10 years. Honda has NEVER offered a DOHC V6 in an Accord, preferring to stick with SOHC. They didn't even bother to offer a V6 of ANY sort until 1994. There were only 2 years since 1991 <1997-1998>where GM didn't offer at least ONE DOHC engine in a mainstream car .... but NO ONE BOUGHT THEM! Could it be something OTHER than DOHC humping was hurting GM at the time? If the GM pushrod V8 sucks so bad, why is it that CTS-V drivers only get to see M5s in their rearview mirror and it took a Porsche of twice the CTS-V's price to beat it around the 'Ring? If the GM pushrod V8 sucks so bad, why is it that the Silverado can out accelerate the F-150 and get better gas mileage while doing it?

I thought LEDs produce less heat.

I would like some input as to what should be included in a review template for any car write ups that we do as a site. Please also offer your opinions on article formatting, points, systems, photography standards, etc.

Not bad!

Different servers can have drastically different results.

LOLPaint? Is that like LOLCat?

I bet he even paid over sticker for the privilege as well.

Seriously, Speakeasy.net has been offering free internet speed tests since.. oh 1999.

spare tire? not likely to be missed

In the Sebring's case it's probably a much safer car simply because people stay away to avoid getting the ugly on them.

Usually, some rental places are pushing it off as a full size now.

Cspec, what's your budget?

The Small Block simply for packaging reasons.

Well I got a full size, so that likely means an Impala or Taurus... maybe a Malibu. If it's the Impala I won't bother. If it's a new Taurus or Malibu, I'll write something up.

You haven't been to Pittsburgh lately. Three years ago I would have agreed with you, but since that time we have a new, massive, convention center that is also a LEED certified green building. Other massive building and reconstruction projects have taken off in the same time frame. We have 1 new skyscraper, also a green building. There are whole city blocks downtown that are being gutted and rebuilt into green buildings but that still retain their original appearance. Two new stadiums with a 3rd being built as another LEED building. A 5th performing arts center is just being finished up, also a green building. And we've held the "Most Livable City in the U.S." title since 2007.

I always recommend ceramics. They'll go 100k miles.
