The liability and failure-potential issues with a cut and welded steering shaft make me shiver. If I were going to do this, the only way I'd accept it would be for the shaft to be cut, both ends drilled and tapped, a high-strength all-thread piece installed with high-grade Loctite, the junction welded, the weld ground down to shaft diameter, and a sleeve welded over the junction (weld bead at each end of the sleeve). Overkill? Yup,
almost definitely.
As for power vs. nonpower: I like the 20:1 nonpower steering in my '62 Lancer with aluminum engine. I tolerate the 24:1 nonpower steering in my '71 Dart with iron engine. I hated the 16:1 nonpower steering in my '65 D'Valiant with aluminum engine, somewhat more than I'd disliked the power steering in the same car. I would hesitate to opt for nonpower steering in a heavy F-body like that. If it were my car, I'd fix the power steering according to my time and money budget: if I had the cash and didn't want to think about the steering box for a long time, I'd put in a nicely built box from Firm Feel or Steer and Gear. If I didn't have the cash and were willing to gamble on having to do it again, I'd swap in a used box.
I would not worry about the weight difference unless I were going racing.
