I wanted the suspension geometry to be correct all the way through the travel arc. Using a OEM cross member there is no way to drop it as low as I want to go and not have excessive camber tilt.
My target is not to lay frame but to be 1" off the ground completely aired out.

I don't have much exposure to the pre-Square HD truck chassis. What is the main frame rail height under the cab?
If it's the same as the Squares (6" height), a 1.5" x-member notch/pancake w/3" spindles put my frame rails & x-member gusset bars on the ground @ the same time when completely aired out (PB 1" forward lowers + modified stock uppers w/the stock GM steering placement). Ride height @ the rails is 4.5 -5" @ front cab mount (29.5F/31.5R).
I would of guessed the full PB set-up would put the rails on the ground before mine. What height tires ?

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....
Cubic inches is like Indiana Jones with a cheap pistol.
