I have not seen the new vehicle inside the hood yet, so here's a dumb question, what is the deal with the 3.9 L engine they are using? Is this a bored and stroked version of the new 3.6 DOHC high tech engine, or just a bored out version of the 3.8 pushrod engine with VVT added? The 280 or so HP they quote it generating is fairly decent, so i'm thinking its a OHC model. If someone knows the details that would be nice to know. GM just says the deplacement and power ratings, they don't usually like you to know its a "outdated" pushrod design in the literature.
