1/4 mile car front end alignment

Car-67 Valiant with new: QA1 k-frame,QA1 lower arms,QA1 upper arms,New .810 MP torsion bars,New inner and outer tie rod ends,New spindles with strange disc drag brakes,New comp. eng adjustable shocks set at 90/10,New MT et front tires, so our goal was 0 degrees camber,6 degrees positive castor and 1/16 toe in ,We purchased the fasttrax castor/camber gauges to do alignment,Out of all the reading I did on the subject with drag car front ends I came to conclusion to align the car at "track attitude" meaning the front end is lifted thru out the run,After watching video's on the car we set the car at what we thought the height should be and proceeded to align the front end and we met out requirements but here is the rub we have,When the car is set back down and not at run height we get 2 degrees of negative camber with the weight on the front end???? is this normal??? as soon as we load the chassis it goes right to what we want at--o degrees camber-6 degrees castor and out 1/16 toe in,So were kinda confused cause this is our first time doing this and are learning--Thanks Steve
