How High?

I have the 4" cst spindle lift on my truck now and now have that sickness of going higher. I was looking into the spacer up front and a 2.5" deaver out back. My question is How much higher can you go on a spindle lift and spacer combo? Is it possible to get that 8" lift in front without cutting and welding anything? I want to be at the highest point for a 2wd without all that custom fabbing.
