D-150 rear springs for drag racing

I was taking some measurements on the truck today. To get the truck to sit level the rear would have to drop 4". The leaf springs aren't symmetrical like I thought, but they aren't the same as the muscle car springs either. The front segment is 24" long and the rear segment is 28" long. I know the Mopar Performance Super Stock springs are designed to lift the rear of the car under hard acceleration to help plant the tires into the track. So I don't think the Truck springs will react the same as car springs. So for my application should I have the truck sitting close to level and just hope for enough weight transfer? Leveling the truck I should get more weight transfer than I would have now with the *** end 4" in the air.
