I've got the 49 page orange brochure; its OK for average consumers but the lack of real mechanical specs wouldn't pass muster if they were selling commercially. Doesn't even list gear ratios.

I'm familiar with 4WD systems including Jeep's systems. Since 4WD/AWD systems range from primitive (Jeep TJ) to highly adaptive (Audi/Torsen), I'd like to understand what kind of system I'm buying. I'm not keen on a chip deciding whether I need my rear axle locked or not. Most 4WD mfrs provide a lot more info on how their systems work for mechanical geeks like me.

I'd also like to be sure the Vortec 3500 uses cast iron cylinder liners in the aluminum block. I checked several Vortec engine websites, and none mention it. It should be agiven, but with GM ya just never know!
