RE: Shocks/Suspension Dropping
Softer will just make it droop more. Firmer will help out on springs. I would try adjusting the oil weight a bit and a slightly stiffer spring and set your rear drive shafts after a 6 to 8 inch drop so it rebounds parallel to the surface your dropping on. You might with the new motor have to adjust the one side more. Bigger is nice but also means more weight.
