That would be quite the accomplishment since the Taurus SHO is barely managing 22mpg highway as it is, I don't think fuel mileage would improve by putting it in an F-150.

I see where you're going. I think the death of the pushrod V6 was brought on more by the advances in 4-cylinder technology. I think we'll see more ecoboost type 4cylinders in the very near future and we're unlikely to see many, if any, more small displacement V6es of any kind. I'll take a stab and say that 3.5litres will likely be the new floor for new V6 engines. Any V6 coming out, not in development today, will be 3.5 liters or larger. I think the same effect will happen on V8s a bit further down the road. Ford is already proving that with the ecoboost V6es. The problem here is that 4.0 liters is likely the largest Ford can go on an ecoboost V6. This is where the pushrod comes back into play. There is no reason GM couldn't turbo or supercharge a medium displacement pushrod V8. The 5.3 puts out 315hp today as a naturally aspirated engine. GM could throw a supercharger on that very easily and have a 400+ hp engine that will fit in the space a N/A DOHC engine could fit. Turbos and DOHCs take up a lot of space remember.

You don't seem to understand, in SMKland, if it doesn't have DOHC, it doesn't matter if it beats the competition in every single test, it still loses.

You're full of it basing your estimates of what can and cannot be done from an engine that, while many here appreciate, is admittedly very old tech. The pushrod 3.5 also did 200hp with no great leaps in engineering. I'd be curious as to how big the exterior dimensions of the 3.5 liter ecoboost are compared to the exterior dimensions of the 5.3. I'd guess they are roughly the same. Which means that the 6 liter could also fit in the same physical space, making your ecoboost point rather moot.

I hope we don't get the shortsighted goverment restrictions on engine displacement. That's what the Euros have done. The previous generation Malibu V6 would get better highway mileage than the Camry 4-cylinder because it had better torque at a low RPM. Displacement doesn't always mean poor mileage.

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 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?
