So what do you guys think, am I doing something wrong?
Have Qa1's all around with qa1 springs up front and stockers out back
bmr adjustable panhard
bmr adjustable t/a mounted to my turbo 400 crossmember
bmr extreme duty rear swaybar
bmr lca relocate brackets and badz adjustable rod ended lca's to go in them (right now have lakewood non adjustables in the stock hole)
subframe connectors
I have the pinion angle set at -1.5 and I have tried all sorts of different combo's with the shocks and I just cannot get the car to hook!!! Got a turbo 400 coming off the t-brake with spray w/ 3.73's and 28" ET Drags. Any suggestions on shock settings to try, or pinion angles to try or what not would be appreciated!!! Or if anyone knows anyone in florida that is good with setting up our cars, let me know, cuz I really need it!!!

Tried all different settings on shocks, started at 3 up front and 7 out back which is where she hooked pretty good on motor and it wouldn't hook very well, so I started making drastic changes and tried 4 up front and 3 out back cuz coach told me to try that once, and it hooked a little better, so then I tried 6 up front and 4 out back cuz big mike told me to try that once, and it hooked pretty close to the same as 4 and 3, but no matter what it was always spinning pretty bad!!!
I have the pinion angle at -1.5 setting it the way it says too on bmr's site with the pinion and driveshaft angles, and i'm not sure what you mean by angle of attack on the lca's? Right now I have lakewood non-adjustables in the stock hole on my relocate brackets, waitin for my badz adjustables to come in so I can go to the bottom hole, but not sure how much that will help. Also, the track prep usually isn't spectacular on a TnT night, so that plays into it a bit too! And I keep the tires at 12 psi cold.
Oh and forgot to mention the shocks are regular f series hals. And I also have my front left spring a little higher than the front right to try and put a little more weight on the right rear, but not sure how much cuz I don't have scales, it's about 1/8 - 1/4 of an inch higher than the right, a few people at the track told me to try that.

Shocks normally I start at 3 front and 6 rear. Your tires are close. What I do is have some one stand behind the car and look at the marks you leave when the car launches. You are looking for an even black track the same width as the tire. If the marks are darker on the outside then it needs air, lighter on the outside less air.

So if ur on a garbage track and 3 and 6 doesn't hook, which way do you start adjusting them, so I have an idea of what to do to get her leavin at our track?

Loudmouth LS1, You have gotten some really good advise from Madman and others. I would like to add something about the converter stall. I would contact the manufacture and give them the exact specs of the car and be clear an honest about what you want from the car/converter and what you a going to be doing with the car. It mite be in your best interest to sell the converter you have and get on specific to your application. I don't know much about the ss4000, but many of the street-strip converters are not very well suited to t-brake & sprayed launches. Converter technology as progrressed by leaps and bounds in the last few years and the the converter companys have become very efficient with nos converters.
Good Racing and Good luck!
