Can you help me get 12's in the quarter and 15 mpg or better?

Low gears and overdrive. 26" slick for drag racing and a taller tire for highway use. Do you have any running motors available to you now? Budget? What axle and gears are installed in the car now?
Currently i dont have any running motors or even a block for the matter but im looking to buy a 360, stock axle and gears
