Found this while perusing the Wikipedia article on variable valve timing.

Interesting. This sounds similar to the technology they're using in the new Viper. It's suppose to be two tubes that make up the entire cam, where one allows the other (being the one with the cam lobs attached) to rotate depending on the engine speed.

Yep. And that article is from 1991.
