Go to pages 30-32 (Numbering on the actual pages, not the
pdf counter.) From the lats paragraph of page 32;
"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. We may
not see a four-valve pushrod gasoline engine,
despite use of that valvetrain in diesel
V8s. However, cam-in-block pushrod
gasoline engines have a high-tech, highperformance
future, and both Chrysler
Group and GM keep engineering teams
on the job of developing it."

I think the V-Max 6.0 V8 in the new Silverado has VVT, so it sounds like Chevy is positioned to apply this technology on other engine platforms like the C-6.

The 6.2L in the Escalade is VVT.

Variable valve timing (VVT) helps optimize camshaft timing to improve low-rpm torque and high-rpm horsepower. The introduction of variable valve timing through the unique dual-equal cam phaser is the industry’s first application of VVT on a mass-produced V-8 overhead valve engine. The unique dual-equal phaser adjusts the camshaft timing at the same rate for both the intake and exhaust valves.

The VVT seems to make lots of power and pretty good fuel mileage. Plus it has a nice smooth liner power band. It's actually fun to drive.

I'm lost in the translation, but impressed non the less.
