Steering question

[Happyfunballs]

I figured this section was as good as any to post this. I've got a few extra bucks and would like to upgrade the stock steering on my 67 Camaro. I have 2" drop spindles on the front which might be an issue with rack and pinion. Which is better, rack and pinion or an upgraded steering box with the stock drag link/tie rod end setup? Would I need to change out my Saginaw steering pump? I need some schoolin.

:edit-I have a 7 quart oil pan as well, which very well might exempt me from the rack idea. Thoughts?
