With my 3.73s I can get 28 MPG on the highway as long as I keep the RPMs at or below 2K which means 65 MPH. it seems the MPG go down above 2K RPMs. I do make quite a few road trips but considering I was use to 12-13 MPGs with my old Big Block I am quite happy with the 28.
. Oh yeah, as far as performance I love chirping second and third.
