My question though, is this: has anyone ever played with rear gear ratios on these things? At 70 mph, the engine's running at 3000 rpm. For all I know, that's the sweet spot in this engine and the best it's going to do. It's just that, at least by the seat of my pants, it feels like this engine has way more torque below 2000 rpm than at 3000, and if it could keep the vehicle cruising at speed in that range, it should get way better mileage. I know that most modern vehicles with V-8's (I realize, a completely different application) cruise at 70 mph at 1800 rpm. Maybe the 3.3 doesn't have the torque to keep up and has to depend on horsepower? Anybody experiment with this? Thanks...
