Dennis, before doing anything ,check the rear to see if it is straight in the car.
This can be done simply with a string and tape measure.
If the rear is straight, check the corner weights withe the drivers weight in the car .
Take all preload out of the bars ,both sides, and measure ride heights at all 4 corners .
If the height is not equal side to side ,both front and back start there.
If it is equal, look at the corner weights with no preload. ....dont get too carried away with ballasting the right rear, get it close to equal side to side ,but dont go overboard.
You should never need to add more than 50# preload with the bar to go straight.
Keep in mind most stock chassis cars will always have a little more weight on the L/F wheel due to engine / driver location ,as opposed to a full chassis car.
If the chassis is rolling while in the air staggering the rear shock rebound may help slow it down.
It sounds like you may have just a little more HP in it than a Stocker might have .
In that case you may want to consider adding an anti roll bar.
That will help keep it flat on a long ,high wheelie.
