Front suspension options

You also mentioned Edelbrock shocks, but haven't mentioned what size torsion bars you're using.

With all do respect, here's what some of the guys are trying to tell you: What you call "properly set up" is considered a "very mild upgrade" for many folks around here. Unless your t-bars are at least 1" dia and you're using much better shocks and tires, you're not even close to the upper limits of A-body suspension. If you'd maxed everything out and then said "not good enough", I could understand. But the fact that you're not familiar with the Borgeson steering box tells me that you have some more investigation and research before I'd go with something as radical as you're proposing.

Having said that, if you proceed down this path anyway, I'd read everything you're willing to post about the swap, and wish you the best of luck!

With all due respect, I think what you, and others, are missing is that I'm not trying for a maxed out, tuned to the nth degree, auto x or drag race front suspension. Where all of you get this idea that everything has to be the best handling, or lightest weight, top of the line suspension, or it isn't worth it, is beyond me. I was merely thinking about options for a suspension that handles as well as stock, gave better room for headers, parts are readily available, updated to R&P steering, and was reasonably affordable. Those are things that would make it worth it to me, and that is all that matters.

If I ever were to go down this path, I promise, I will document the whole process and report my results whether good or bad.
