I think 33-35 mpg's will be no problem in real world driving. When I did the power tour in my baby cammed/bolt-on 99 trans am with a 6-speed and 3.42's I was doing 27-28 mpg's with the ac blasting. Guys that I traveled with did 30-32 in there stock vettes so this should do very well IMO.
I like my woman like my milk shakes, THICK!!!!
