Sounds like you are running 165/60/15's? That should lower the front without running the adjuster screw too much.
Just be carefull you don't go too low. You will bottom out the lower control arm to the frame. With the 440 and /6 T-bars it will be easy to bottom out on the street.
Sounds like a drag car. Does you oil pan sit lower than your k-member?
FWIW, the top of my front wheel lip arches are 24.75" from the ground and the lowest part of my k-member is 5.5" from the ground.
