How low can I go w/o bags?

[spartakus]

Today in the garage, I'm doing a little mock up to figure out my ride height and frame rake and wheel centerlines, so I can weld in the suspension stuff.

I have the TCI custom IFS front suspension w/ 2" drop spindles & the TCI 4 link rear. All w/ adjustable coil overs. I'm also going to be putting in a 5.3 LM7 w/ a 4L60E w/ an 8.8" ford rear.

I have had the idea/picture in my mind for a long time of how it should sit based on other trucks I have seen in person or in pictures and I've got the frame kinda sitting that way right now but,... the frame seems awful low?

Right now my very front bottom tip of my frame is about 7" from the floor & the very front lowest part of my running boards is about 6 3/4" from the floor. This is close to what I want and now Im worried that the front of the frame/crossmember/oil pan/etc are gonna be too low?

Anybody else have a similar set up w/ experience here? Am I safe or too low? What do you think?

Thanks for any help
