Mustang II vs. Mopar torsion bars?

[lantzn]

I've purchased the two Huntimer books on GM and Ford pro-touring. I'm more familar with Mopars because I've restored a number of them in the 80s. I'm currently in the planning stages of my first pro-touring type project. In another post I stated my initial plans. One of my biggest areas of interest is on suspension and bracing. This 68 Barracuda coupe is going to be my daily driver. I want performance and comfort.

1. Would there be a huge difference in adding one of the Alterkation front ends that take advantage of the Mustang II suspension compared to going with a beefed up torsion bar setup for the 360/300hp engine?
This would be the stock slant 6 k-member, 225 to 360 motor mount conversion kit, 340 rated torsion bars, adjustable UCA, reinforced LCA (Firmfeel), high performance shocks, 74 a-body spindle, Wilwood disc brake kit, polyurethane busingings, heavy duty parts whereever and fast ratio steering box.
What about the difference between a power or fast ratio manual steering setup? Would manual steering on a daily driver be a pain?

2. What about bracing? I want to take full advantage of the interior for myself and passengers. I can't imagine a roll cage would allow me this. What extra supporting would you perform throughout the car. The car is stripped to a shell and so this is the first priority while having the little bit of rust repair being done.
