General Motors LSX454R crate engine at Barrett-Jackson - Click above for high-res image gallery
It's not just cars and trucks that are auctioned off each and every year at Barrett-Jackson. For instance, General Motors decided to roll out its latest crate engine, the LSX454R, in front of the crowds in Scottsdale, and proceeds will be donated to the American Heart Association.
Of course, this is no ordinary motor. In fact, at 750 horsepower, the LSX454R is the most powerful engine General Motors has ever offered for sale... and that includes all the barn-storming engines of the Gods the automaker let out in the heyday of the muscle car era.
The 13:1 compression ratio of this engine means it's meant for racing applications and 110-octane fuel, so don't go getting any ideas of the LSX454R under the hood of a shiny new Camaro. Instead, expect to see it occupying the engine bays of 9-second bracket racers at a quarter-mile near you in no time flat.
