Hello. I have a nearly stock '88 LX 5.0 with AOD. If I drive right, I get 19 MPG around town and 21 on the highway. I'd like to get 30 MPG and not kill my power. I knew a mechanic back in the 80's that had an early Fox body with a 302 that got 30 MPG all the time. He died a couple of years ago and now I can't ask him how to do it. I did get 26 MPG out of mine on a trip from home in low elevation, humid Texas to dry, high elevation Denver. I stayed between 75 to 85 MPH most of the way and had go up to 90 MPH in Colorado to keep from getting ran over. The closer I got to Denver on my trip, the better my mileage, but my power lessened. On my trip back home my mileage lessened, but my power returned. It seems like the thinner air in Colorado would have hurt my mileage. A few things I am considering is trading the AOD for a T5 and using 1.5" equal length, long tube headers. I already have a 2.5" off-road h-pipe with Super 40's and no tailpipes. I think the March ram air setup might help also. Is there a better intake or anything else that might help? What about turbocharging? Would a Mass Air conversion do anything for me? I'd appreciate any help you can give. Gas prices are killing me.
