2" lift leaf springs

So I was looking at doing 2" lift leaf springs with offset shackles to move my rear springs in as much as possible, I'm going to be installing a shortened ford 8.8 rear out of a ford explorer. Does anyone have this combo, I have a few questions as to what shocks I should run and also I was thinking about running 15x8s with 275/60s. Will 2" springs be too high in the back? Can I squeeze wider tires that a 275? I don't mind if they stick out a little bit. It will be a summer driver but going for the 70s drag car look. I was thinking of using the jegs SSR star wheels
