Supercharged 6.4L in a 64 Valiant

I am taking all the notes... I did get the Dart convertible project The Yard Dart, a Reclamation. '64 Dart GT Ragtop and am really absorbing all of this info. A question or two: Does the four link setup have bump stops? Rubber?
I know that you selected an area of the floor pan to raise in order to provide muffler clearance; could you elaborate on what area you raised, how much and, looking back on it after install, would you do it the same if doing another? What are the wheel/tire size on the front?
My project build will hope to emulate much of yours. I even traded up welding machines and am practicing TIG welds... I plan to copy the mini-tubs, trans mount, cross member, tunnel, the whole thing. I have the (early version) AlterKtion and a leaf-sprung 8-3/4. I am considering the four link. Watching you project closely. thank you for sharing this.

I just eyeball it with the muffler I'm going to use. Anything is better. I've done this on my last several builds. Got tired of exhaust dragging/scraping. What are the wheel/tire size on the front? 18 X 7 Wheels. 225/40/18 Tires.
