    I suggest you goto www.gmpowertrain.com. The current 5.3 Vortecs have VVT which is done through the cam phaser.

    The current 2012/13 5.3. Like I said before that doesnt matter because its not very effective.

    Its a good motor if you want it for speed i would buy it with the s10. But it tows my 21' boat just fine. Im running magnaflow catalytic converters and magnaflow muffler and im happy with it. Mines an 06

    Riiiiiight. I guess that when GM started using VVT over a decade ago, the tremendous HP increase, and the MPG increase they got from that isn't effective at all. You're just in denial. Sorry.
