C20 Longhorn front leveling clarification?

[asickber]

I've been researching this and would like some confirmation before I proceed in trying to lift the front to level things out. My Longhorn has a BB and AC and all Longhorns are sitting on one ton frames from my understanding. I've seen where people have used Moog 6454 coils to get the desired results ( http://67-72chevytrucks.com/vboard/s...ight=C20+level). It seems that the Moog 6454 will level out a C20 SBC no AC truck. Would it be enough spring to level out a BB AC Longhorn?
