454SS on 'bags??

[dieseleagle04]

I have a 1990 454SS that I'm looking to drop on the ground.. Maybe a 5-7 drop? Problem is I've never done anything with airbags outside of heavy trucks. I'm wondering how hard this is and just hjow involved it is. If anyone could steer me toward some part numbers for a SS chassis that would be great.. I know the suspension is more heavy duty than the single cab short bed but they'd be changed anyway. But I guess what I'm getting at is... Has anyone ever done this on a 454SS? Does the engine size change the way mods have to be done? Thanks in advance.
