If there's someone in your area that has scales, i'd have them scale the car. My car used to go sky high and either go left or right. My is a 4 link car though.
I had a friend/builder scale the car set the CG and preload, bettered the 60' by .003/.004 and only picks up the left front about 4" now. I don't even need the wheelie bar now .543 gear, 14X32's leaving @ 4200 on brake with a 5500 stall converter, car weighs 3253 lbs.
Cost was $250.00 for the whole setup and well worth it.
