I wanted to raise my 77 F150 4x4 truck up enough for 38s before. But now i want to go with just 35 inch Super Swampers should i go with a 3 inch body lift,6.5 suspension Super lift kit, or the 4inch suspension lift from Super Lift. I want room left in the wheel wells i dont want the tires right in the fender. I want to go with 400 or 425hp and 475 or 500 tq can i run with just leaf springs and torsion bars or in the back should i go with leaf springs and ladder bars?

thanks
Curtis
