The SAE techbriefs is a can't miss favorite of mine to read. The April 2007 edition shows you why:

After you read the interesting article on GM's 2.9l V6 diesel PCCI (pre-mixed charge compresion ignition) technology, scroll on down to the end of the article & read about the Viper's V10 with cam-in-cam variable valve timing. Note the quote in the tail paragraph:

Although the Viper SRT V10 VVT valvetrain now is the technology leader for cam-in-block engines, it’s known that GM has a small-block V8 in development with variable intake- and exhaust-valve timing in a three-valve configuration.

This engine has been around for quite some time, predating the LS7, and was discussed in far more detail in a much earlier tech brief.
