generally you want the lower bar to be parallel with the ground to start. you should have a 1-2 degree pinion angle. on very level ground you should be able to take the front bolt out of the bar, just try one at a time then put it back before trying the other side. the is called neutral, which means no preload. with an auto you want to get the back to raise 5-6" on launch with good weight transfer. meaning the front is raising up good. if you don't get the rear to raise move the front of the bar up one hole. if your getting to much raise lower the front of the bar down one hole. always recheck the pinion angle after you move the front of the bar and reset it if need be. if the hotrod moves to the right off launch turn the adjusting bar nut on the right bar one flat only to extend the bar forward. this puts a little preload on the bar to drive the hotrod back straight. it's works just the opposite if the hotrod moves to the left. if this helps but not enough turn the nut another flat. paint the adjusting bar nut on one flat so you can keep track of what you are doing.
