73' B3 340 Duster pro touring build

I love your garage, i wish I had that kind of space to work in. The rear stance looks great, is there no way to get the front a little lower, rather than raising the rear? As you know, wheels, tires and stance are what make or break a car.

I'm crunching the numbers to see just how low I can go and still feel safe on Ohio roads...any thoughts? I'm waiting on my TTI 1 7/8" headers to see how they fit, I ordered them "Raw" so I could do some modifications" like I said earlier I currently have 5 1/2" to the frame near the torsion bar crossmember and 5 3/4" to the rear of the Milodon pro touring oil pan and 6"+ to the front of the K frame. Any of you lowered guys want to shoot me some numbers it would be appreciated....How low are the alterkation suspensions running for ground clearance ?

P.S.- the garage isn't mine....it's my Dad's, trust me I wish I had it too.
