I don't think the antiroll is going to help you, i think you need too soften up the shocks and maybe lower the front of the ladder bars. i know 3 people local that have installed them and then removed them, they are all 4 link cars though. The pic. below is a local ladder bar truck stock frame that weighs over 3,000 lbs and runs mid 8's on a 572" gas motor (no nitrous) has run 8.13@178 with nitrous. He tried an antiroll and then removed it. He carries the wheels about 18" up for atleast 100' is deadly consistent.
