New Lift on my 71 Blazer

[OLD SKOOL K5]

I'm at work for 72 hrs so I can't measure the distance between the crossmember and the oil pan but if i had to guess it's 1 to 1 1/2 in clearance. the brake lines are stock as there is still plenty of room to for flex.
As far as route 66, that sounds like a fun cruise. Have to let me Know the details.
If you are wondering about garage clearence the truck comes in at 6' 8", so it fits in the 7' garage with no problem.
