Rear gear help

not that gas is not a BIGGIE..I just mean that gas has to go in anyways,....and I'm sure the gas milage on the DUSPAN will be around what my truck gets the way I drive..and we build our cars to drive....The Duster now just goes to some car cruises during the week..maybe 30 miles away the furthest...car shows on weekends..furthest maybe 60 miles.SHE has 3.23 gears now...but with the stroker..I would like to have a little more fun..
Just want the car to have some get up and go if I were to race it..I mean run it...so a gear that will have some driveablity and some get up...3.91 would be nice...3.73 would also...and 3.55 would be a good drive all around gear...CONFUSED....
