    ZR1 In A Box: GM Performance Parts Carting LS9 Crate Engine To SEMA

    GM Performance Parts has announced the introduction of its 638 HP LS9 crate motor, set to debut at the SEMA show next week. Yep, the supercharged, 6.2-liter heart of the ZR1 can now be ordered without the Corvette wrapper, ready to drop into the bare engine bay of your choice. You get a complete engine including the ignition system, supercharger assembly, exhaust manifolds, dry-sump oil pan and provisions for the intercooler's liquid cooling system — pretty much everything in this gorgeous exploded LS9 view except the 'Vette engine cover. Pricing isn't mentioned, but considering an LS7 crate engine runs about $14k, figure well north of there. Plus a home-built Lamborghini to put it in, of course. Full release below the jump.

    2009 Corvette ZR1 Power Numbers Finalized: LS9 V8 Hits 638 HP!

    We got a release from the folks at the General yesterday, and we were told we could run it at midnight-plus-one, but then we forgot about it. These things happen, you know. We mean, who gets excited about something as fait accompli as the 2009 Corvette ZR1 getting just over 620 HP? Well, if your answer is everyone, you're probably right. And why shouldn't we be excited about Zee new Really fast One from Chevy? Especially since they've now got officially certified power ratings on that beautiful Jakegasmic LS9 engine — 638 HP, nearly 103 horses per liter — and 604 lb-ft of torque, which'll let the new supercharged Corvette ZR1 break that all-important 200 MPH speed barrier. We knew there was a reason we liked this from the moment we first exploded the LS9 for all to see. Next question however is whether Wes will be back in the road test saddle in time for what we're expecting will be a summertime drive of the new ZR1 or whether it'll have to be one of us other Jalops jumping behind the wheel of the supercharged new Corvette. This may be the first time we've ever hoped someone wouldn't get better as quickly as possible. We kid. On the square. Anyway, what we do know is we've got the full press release after the jump.
