Hi!
Could someone tell me what rearend gears I have by this information? It's a
1991 Mustang 5.0 LX with an AOD, and it's running around 1400rpms at 55 mph (in overdrive). I suspect it's 2.73, but I'm not sure.. If so, what would be the best gears to swap it with? I want to maintain some of the excellent gasmileage I've got to day, but also a little more punch at the redlight.. :)Also, would I get any extra horses by installing a larger throttlebody and an open airfilter?
