The Chevy small block V8 has been around in one form or another longer than many current GM engineers have been alive, but continuous updates continue to keep the venerable powerplant relevant. GM is currently developing the world's first overhead valve Direct Injection engine, giving the 6.2L test engine big gains in horsepower and torque while bumping fuel economy from 3% to 6%.The 6.2L currently pumps out up to 403HP without DI in the Escallade, but Dave Sczomak, development engineer-GM Powertrain Advanced Engineering, says the technology will bump power to "well over 450HP."

Perhaps even more exciting is the possibility that the anxiously awaited Camaro may receive a variant of the engine. The mere thought of the ultra-sexy Camaro packing over 450HP without added boost could make us want to have a smoke. While we're hoping the Camaro gets the DI engine, the halo status of the Corvette makes the two-seater a shoo-in for the improved engine. That would give the base 'Vette nearly 500HP, and it boggles the mind to imagine the output of a Z06/SS/Blue Devil.

Editor's Note: There's no reason to believe GM wouldn't drop the DI V8 in both Corvette and Camaro. Back in December, a source we spoke to who was familiar with Camaro powertrain discussions told us that there was a faction pushing for seriously big power in the Camaro. When we asked exactly how big, the individual smiled and held up five fingers. We'll learn how that pans out in due course. Then in January at NAIAS, Ed Peper specifically told us that there were no concerns with having Camaro step on Corvette, power-wise, as the two cars have such different market positioning -- sports car vs. muscle car. Plus, the ZR1 ensures that there will be a Corvette with power that greatly exceeds that of Camaro anyway. No matter how things play out, there's good reason to expect some real excitement.

      worlds first OHV DI engine? I think you mean first pushrod DI engine.
        • 8 Years Ago
        @ evlfred:

        OHV = overhead valve = pushrod
        OHC = overhead cam = SOHC/DOHC
        • 8 Years Ago
        All OHC engines are also OHV (but not the other way around). Pushrod engines are just OHV without OHC.

        Chris really means "world's first overhead valve Direct Injection engine that's not also overhead cam".

      Wow. Only a year? And they've been hyping it for at least 2?

      • 8 Years Ago
      Honestly, this car is only hyped because it is such an awesome car. You all seem to forget how long it takes to take a concept to production, especially when the platform wasn't even developed yet. I don't think interest will really drop in the next year at all.
      • 8 Years Ago
      I may be run out of town for saying this, but I think it would make a heck of a lot more sense to get the Z28 to market with a 5.3L V8 and around 400hp with DI instead. That would allow it to get much better gas mileage, allowing GM to be one step ahead of the rest of the muscle cars in this rejuvenated power war. And it would still soundly trounce both the Mustang GT and the Challenger RT in all performance categories. Save the 500hp 6.2L for the SS model (which would then target the GT500 and the Challenger SRT-8).
        • 8 Years Ago
        no reason that you should have to jump from the 260 v6 (maybe the direct inject 300 hp standard?) to a 500+ hp 6.2 smallblock. a 350 ish 5.3 would make a great z28.
        • 8 Years Ago
        Good idea. I had a v6 camaro in my youth--don't wan that embarrasment again. But I doubt I could swing an SS model. A good old Z-28 is what I want. Give me 350 HP and a 6-speed, and I'm happy.

        I truly don't want a "halo" car--I just want a freakin' Z-28.

      I'll have a kidney on eBay in an hour if this is true.

      I will get my camaro, challenger, charger, and my mustang as preowned vehicles ,I'm not paying more than 25/32k for a fully loaded muscle car
      • 8 Years Ago
      GM's right. The Camaro and Corvette appeal to different market positions.

      Camaro: Mullet
      Corvette: Grey/no hair.
        • 8 Years Ago
        Who said anything about Civics?

        Calm down man, they make a pill... don't worry about it. It happens to lots of guys.
        • 8 Years Ago
        Don't forget

        Corvette: Small penis
        • 8 Years Ago
        Don't even own a corvette. Some kid in a Civic pissed me off the other day running his mouth and my 1990 JEEP CHEROKEE wasted him in a "race."

        Just gets annoying when people try and read a good peice of news that they care about and then you have morons that get on their and post pointless posts for no other reason then .... well I guess the just do it because they can.

        Anyway... I'm with the guy that is willing to give up his organs for one of these!! I'm hopefully going to start working at a big dealership here in a month or so if all goes through so I can't wait to get one in!
        • 8 Years Ago
        My, my. Touched a nerve there, did we?
      • 8 Years Ago
      Heres the problem GM.. if you hype a car for 3+ years before its available.. people LOSE interest by the time its come out... its not so hot anymore, the design isnt so wowee no more, etc.
        • 8 Years Ago
        Amen Tyk. Apple, Inc. (love 'em or hate 'em) is the ultimate hype machine. Notice how they come out with something that looks cool, sell it immediately, then redesign it in 18 months and start the buzz all over again? GM reminds me of one of those great summer movies that they advertise, you want to see, and then you realize you can't because they're not going to let you see it until it comes out in 4 months. Truthfully, the next time those movies cross my mind is when I stumble across them in the video store a year later. People's attention spans are short. And this new Camaro that no one can buy is already getting a little long in the tooth.
      • 8 Years Ago
      How about GM add variable valve timing first. (The new viper has it, called 'cam-in-cam')
      The 6.2 in the escalade has variable cam timing (one phaser for the entire camshaft)
      • 8 Years Ago
      Not really on topic, but Chevy trucks could really use this for the 5.3 V8. Nissan and Toyota already have far and away more power, and Dodge and Ford are both getting big upgrades next year for MY09.

      400HP is already largely unusable on public roads in a medium sized car, so I don't see the jump to 450 to 500 as being much besides a dick compensator.

      • 8 Years Ago
      Unfortunately were I work we sell Pontiac so I'm stuck waiting to see if a fire chicken is released.
      • 8 Years Ago
      The production Camaro will be smaller than the concept. We are only about 18months away from production at my guess and the design is very good. Some cars can be out for years and still not look old while others have a much shorter shelf life.

      350z and RX8 have been out for 4 years and still look good while the 300C has been around the same I think and is starting to look dated.

      As long as there is plenty of power, reasonable handling and a reasonable interior Chevy will sell many of these. And I'm someone who would never have owned a Camaro before.
