vortec max MPG? And more ?

We get the same in our VMAX, and the magic is all in the manifold and supercharger

I'm not following how this is actually gonna work? But if it does it sure sounds like justification for a go fast part to me!

I drive almost exclusively all city. I think it just requires a lot less pedal to get up and go than it did with the 3.42s. Also the engine doesn't lug around like it did with the 3.42s in 4th around 40mph

no joke either in my experience the 6.0 gets better highway gas mileage than the 4.8. I've never had the 6.0 kick down to 3rd on the highway going up a hill whereas the 4.8 would have to kick down all the time, even unloaded.

well nvm on this idea, the dealer sold it out from under me! Sold it after I said on the phone I wanted it, glad I called them one more time for a question about something completely off the wall before I drove 2 1/2 hours.
