If you're perplexed as to why anyone would pay $5,800 to build their own already-paid-for engine in a new 2011 Chevrolet Corvette ZR1 or Z06, you're not alone. However, at next week’s SEMA event, show goers will get the chance to experience the live build of a supercharged 6.2-liter LS9 V-8 engine destined for a Corvette ZR1 supercar.

That’s because Chevrolet will be exhibiting a “build your own” Corvette engine demonstration, an experience customers usually pay $5,800 for. While attendees of the SEMA show won’t actually be able to help build the engine--that privilege goes to skilled engine builders from General Motors’ Performance Build Center (PBC)--they will at least get to watch and ask questions as the engine comes together.

For anyone who’s been living under a rock for the past year, the LS9 engine produces 638 horsepower and propels the Corvette ZR1 from 0-60 mph in just 3.4 seconds. It’s built with titanium connecting rods, forged pistons, a dry sump oiling system and four-lobe 2.3-liter supercharger.

The 2010 SEMA show kicks off on November 2 in Las Vegas, Nevada. If you can’t happen to make it to the show, you can at least watch a video of the Corvette engine build experience by clicking here.
