Randy,

At this point I'm not sure what my car will do yet, because I'm trying for that one ten second slip too. I can tell you my shackles in the stock position are similar to yours. I've added a 1/2" aluminum plates in front of the front hanger to get about 45 degrees. The shackle position will allow the car to rise a lot more(push down), so you have to control it with your shocks. Also, if you need a set of B body springs to try. I have both xhd and ss for b bodies. I got a great deal on some tri city launchers and have them on now. I really like them a lot as they lowered the car in the rear. I have 5" of rise in the front end and added the calvert shocks. What a difference. I've really concentrated on gettin 5" of rise in the front end. Big difference even on the street! I'm looking forward to trying it out at the strip. Dennis
