whys my cars butt sit so high?

iv to a 67 cuda notch, stock style 340 leafs, comp engineering 3 way adjustable shocks, stock shackels and no snubber. the wheel well lip is a good 3-4 inches off the tp of the tire at a standstill and i just dont like how it looks. i know these old mopars suspension was designed to lift and plant the tires on the hit witch the car does and hooks fine. some people i meet like the look of my cars stance cuz it kind of reminds tem of that old prostock style rake but id jut rather have my rear settled down ontop of the tire even if its just down to an inch away. anyway heres some pics of it sitting and launching anybody got some tricks on evening out my rear ride hight without a new susp system????????
