Thinking of going an inch lower

[creepy74]

Hey everyone Im building a 74 c-10 with my gf and it already has a 4/6 drop. It has a flip kit in the back and 2.5 spindles with i belive cut coils or drop coils I cant tell. To me the springs look cut.

Anyways we have new leafs (no drop) and Im almost certian we are goin to need new coils as well and we are thinhking of going and inch lower front and back.

Which would be better to do in the back 1" shackels or 1" blocks? Im thinking shackels.

And in the front are 3" coils going to give us problems?


We are also going from a 350 to a all iron 454 so the added weight is also a concern with the added drop.
