Stick car suspension set up

Hello guys
I’m new to all this and I’m looking for a little help in setting up my suspension.
I just started going to the track this year and I’m having a lot of fun but would like to improve.
I have a 69 Dart, stroked 340, 855 5 speed, 8 3/4 with 410 gears, 255/60 15” ET streets.
My 60 ft sucks lol somewhere in the 2s mostly, any help would be great. Thanks
