What are the exterior physical dimensions of each engine. The LT5 just barely fit in the 'Vette engine bay. What displacement could the pushrod be increased to and still be physically smaller than the DOHC engine?

They already have VVT for the pushrods. Who cares about higher redline? that's what gears are for. Did you just imply that the competitors to the Corvette aren't designed right? Much like a SOHC can still have 4 valves per cylinder, a single pushrod can actuate more than one valve. Perceived refinement is hogwash.... particularly in this segment.

So show us the business case for DOHC in the 'Vette. What does it buy you that the current Vette cannot do now? Why do you have the assumption that VVT and more valves cannot be added to the engine now?

V8 to V8 there SMK, a DOHC V8 has more moving parts and more internal friction than a pushrod

Who said pushrods could only have 2 valves? If you're going to go on about valves and good breathing, why not a 5-valve setup like VW has been using since 2000? Why are Toyota, Honda (which is mostly SOHC btw), BMW, and Nissan so far behind on this?

I don't understand how an engine that weighs more yet has less displacement, has more internal friction, poor packaging options, and a higher center of gravity would be better for performance.... but that's just me....... and GM apparently.

It wasn't just sound. You couldn't even feel it.

You've been told time and time again. DOHC is actually older than pushrod. You've also been told time and time again that the reason pushrods are gone from 4-cylinders (or any inline arrangement) is because there are zero packaging advantages. The V6 pushrods are dying because they've gotten zero investment dollars because even the best DOHC beating pushrod would never satisfy the import humpers like you. You'd find some assinine reason to hate it like "doesn't rev to 8,000 rpm". You've already been shown that blindly choosing a DOHC engine over a pushrod engine will have you looking at Chevy or Cadillac taillights growing smaller in the distance. 99% of non-gearheads don't have a CLUE what the acronym DOHC even stands for let alone means. They only like it "better" because Consumer Reports told them to. The Buick Lucerne I rented had the 3.9 liter pushrod. I drove for 20 miles in 3rd gear at 75mph and the only reason I eventually noticed is because the instant MPG reading seemed a bit low. There is no audible or even visceral difference in the Lucerne at 75mph in 4 or 75mph in 3. 66Stang can back me up on this one, I took him out for a ride in it.

Eldiablobanshee, you found yet another issue from the forum software upgrade. The instructions posted earlier in this thread are no longer valid. I'll get back with updated instructions tomorrow.

Let's not pretend that Ecoboost is anything more than a nice turbo setup. GM is getting 300hp out of it's 2.8 liter "ecoboost" engine in the Cadillac SRX. Some quick math tells me that Cadillac is getting 107hp/liter while Ford is getting 104hp/liter. What would happen if a turbo were put on the 'Vette? More power of course.

The only FWD mid-size coupe that deserves more than one look is the Accord. The poor sales aren't the cause, they are the effect.

GM posts $1.2 billion loss, says it will begin to repay U.S. loans DETROIT -- General Motors Co. posted a $1.15 billion loss during the third quarter following its exit from bankruptcy and spelled out plans to begin repaying $6.7 billion in U.S. loans. "We have significantly more work to do, but today's results provide evidence of the solid foundation we're building for the new GM," CEO Fritz Henderson said in a statement. The "managerial net loss" was for the period of July 10, the day GM exited 39 days of court protection, through Sept. 30. For the full quarter a year earlier, GM had an operating loss of $4.2 billion and a net loss of $2.5 billion. Discussion - GM posts $1.2 billion loss, says it will begin to repay U.S. loans

Time to Vote on Volt Nearly 13,000 consumers submitted entries Every state represented with at least one name entry Consumers vote Nov. 16 through Dec. 1 to decide the winner Winning name will be announced Dec. 1 in Los Angeles DETROIT – “Chargetruse,” “Recharge Silver,” and “Voltaic Platinum” are among the nearly 13,000 entries consumers submitted in Chevrolet Volt’s paint color name contest. Chevrolet has named three finalists whom will compete for a chance to be the first consumer to test-drive a pre-production Chevrolet Volt electric vehicle. Chevrolet selected “EV-ergreen” offered by Devin McQuarrie, 30, of San Jose, CA; “Viridian Joule” submitted by Dave Thomas, 40, of Sanford, FL; and “environMINT” entered by Matthew Valbuena, 30, of Rancho Santa Margarita, CA. Chevrolet chose the three finalists based equally on originality, creativity and the ability to capture the innovation and spirit of the Volt. Consumers now determine the winner by voting for the favorite name of the three at www.chevroletvoltage.com through 8 a.m. ET on Dec. 1. The finalists and a guest each will travel to Los Angeles where the winner will be announced by Chevrolet on Dec. 1. Votes are limited to one per person, per internet protocol address during the voting period. About 27,000 people – or half of all visitors to www.chevroletvoltage.com during the entry period Oct. 22 through Nov. 4 – submitted a color name. The Chevrolet Volt is an electric vehicle with extended-range capability. It can drive up to 40 miles on electricity without using gasoline or producing tailpipe emissions. When the Volt’s lithium-ion battery runs low, an engine/generator seamlessly operates to extend the total driving range to more than 300 miles before refueling or stopping to recharge the battery. Production for the Volt is expected to begin in late 2010. Pricing has not been announced.

I'm calling dibz on the Blazer for the moment.

should be fixed now. let me know

This might end up staying in the C&G family if Camino will let it.

I'll say this. The Regal seems to have changed my vehicle strategy from purchasing a 2007 or newer Avalanche to purchasing an older beater SUV to do apartment work with and saving my sheckels for a new Regal. A Regal coupe would cement this strategy change.

+1 +1 +1

you don't think adding direct injection, an 8-speed DSG, and VVT would add a bit of fuel economy....
