General Motors is getting ready for SEMA 2009, but the Detroit-based automaker has a little over a week before it can show us anything official in Las Vegas. That isn't stopping the General from teasing us, though, as this 40-second YouTube clip clearly demonstrates. One of GM's new tuner specials comes in a box and figures to be packed with power. It's a crate engine, but unfortunately the company isn't giving us much in the way of details.

Hit the jump to watch a pair of technicians bolt the mystery engine onto an unknown frame that already sports four Corvette-badged wheels. We're no trained eye, but the engine looks an awful lot like GM's 5.3-liter mill, which is made at the General's Canadian St. Catherines engine plant. To make us feel even more strongly about the mystery motor being some variant of the 5.3, there is even a Canada sticker at the belt wheel. And since the end of the video says "A new kind of crate engine is coming," at least one Autoblogger is further hypothesizing that the 5.3-liter could be a flex-fuel variant. But like we said, we're just thinking out loud here, so if you have a better guess, let us know in the post-jump comments section. We'll likely know for sure once SEMA begins on November 3.

      ehhh that looks like a larger displacement than 5.3..... I could be wrong who knows. I'm anxious to see that upcoming Gen V direct injection V-8 but that still may be a couple years.

      That's one thing GM can do - the LS series engines are the BEST IN THE WORLD!

      I do not see how you can settle on it being a 5.3 by how it looks. All Chevy engines look pretty much exactly the same. That being said I hope it isn't a crate flex fuel motor identical to an already available motor except flex fuel capable. That would be a lot of hubub over nothing.

        @HotRodzNKustoms
        Exactly - externally speaking there's very little way to tell whether you're looking at a 4.8, a 5.3, a 5.7, a 6.0, a 6.2, or a 7.0L engine. All I can really say, based on the looks, is that looks an awful lot like a LS2 or LS3 intake manifold (the truck 5.3s have much taller intakes), but that could have been swapped. The exhaust manifolds aren't big enough to be the LS7 pieces, so we're probably not looking at a 7.0L, and obviously it's not supercharged.

        Oh, wait, the power steering pump pulley on my LS1 has a Canada sticker too! Does this mean the new crate is a LS1?

        (Hint: GM sources all of those pullies from Canada.)

      That is a 1955-1956 Chevrolet chassis.

        55 - the body is sitting next to the roller.

      "Belt wheel"? I think that's the water pump pulley. Sounds like somebody needs some more automotive knowledge.

      I'M JUST GUESSING BUT IT COULD BE A HIGH REVVING SMALL BLOCK FOR THE UP COMING Z-28.
        • 5 Years Ago
        I could be wrong, but hasn't it been confirmed that the Z28, if/when released, will be using the LSA?
      • 5 Years Ago
      Agreed, A.B.'s proof reading leaves a bit too much to scrutinize.
      GM used to have 3 plants in St.Catharines (Ontario) but most of the Welland Avenue plant was leveled and sold off. IIRC, just the front office building remained but that was more than two recessions or a millennia ago.

      So, it looks like there will be some kind of Tri-Five Chevy with the new crate motor on the floor at SEMA. I am happy to see that even with all the crap GM has gone through in the past year, that they are still attending SEMA, and that Uncle Baracky is letting them do it.

      Dear GM:
      We are still waiting for the aluminum LSX block.
      • 5 Years Ago
      General Motors in St. Catharines (Ontario) is located on ONTARIO Street - NOT Canadian Street.
        • 5 Years Ago
        Actually they have two plants there, Ontario St. (a.k.a components plant) and Glendale Ave. (a.k.a engine plant).

        The Ontario St. plant does not do a whole lot any more and the operations for St. Catharines are all based out of the Glendale Plant.
        • 5 Years Ago
        I misread that too at first.

        They don't mean "Canadian St."... They mean Canadian, St. Catharines.
      • 5 Years Ago
      Can you say "Corvette Racing"?

      ACO rules for 2010 require a 5.5 liter engine.

      A 5.3 liter crate motor (with dry sump) and lots of hp as an over-the-counter option stisfies certain rules and homologation aspects.

      it's a shame gm won't put the 4.5 liter diesel plant to work and make those in a crate package.
