Low end, torque?
 

I've got an 85 N/A, automatic. It has plenty of top end, kicks into 4th at 120mph, but takes forever to get off the line. What can I do for some more torque? I don't mind sacraficing that top end for some torque. I rarely drive 130 through town!! Any info on this would greatly be appreciated.
What can I do, and where can I get it??
