Ever since I installed my 4 inch suspension lift I have had a sag in my rear leaf springs. My truck was stored for 10 years with a heavy chain in the box. We rearched the springs before installing. I have been running 305x70R16 and I like the look of the smaller wheel well with that size of tire. I still kick myself for not going with 35"s. I was wondering if I could drop the front end to match the rear.
I am going to swap my sbc for a blown bbc 427. I would think that the bbc should drop the front end a little. Although there is like 6 leafs in the front and only 3 in the back.
Hear are my measurements to the top of the wheeel well.
