70 C10 lowering questions

[mm1077]

Just wondering if anyone could give an opinion on if I'm headed in the right direction on lowering my 70 C10 lwb (I've read a ton of info on here and online but just want to be sure before I start ordering stuff)...

I have new 275/60/15 all the way around, looking at 4" drop springs for the rear (could I just add a 1" block if I wanted to go lower?) and a set of drop shocks...I was just going to cut 1 coil off of the front and use drop shocks (or relocate the current shocks) + alignment. Any opinions on whether I would run into clearance issues w/ the 275's on the front w/ just cutting the 1 coil? Anything else that I would absolutely need to make this happen? Or anyone have pics of a similar setup w/ the 275's on all four too that would be awesome...
