FWIW : I waited until I had time to measure the bars on my SB Duster (username pic).
It's run the .790 bars for decades, Jack Arnew upper arms (widened, more caster, 0 camber), and modified SS rear leafs.
Upper arms travel-limited using a 1" spacer, car sits with a rake, about 1" off lower arm bumpers.
Footbrake car, 5.38s & 13x31s, pretty light ("extra-legal"
) on the nose from its SS days.
Pitch rotation no problem: with a 460-HP 358 (11.40s) & 4400 stall it'd hike the fronts 6-8" and leave hard.
I got greedy, 640-HP 368, 6000 stall, and put it on the rear bumper for 300 feet.
OK, really good pitch rotation ! - added wheelie bars, low 10s @ 128 or so.
Wheelie bars set 10" off ground, hits 'em every time.
On a good day it'll carry the wheels 100 feet out, sets down nice, goes straight as a string with about 7 deg + caster.
(Don't stick your wrist between the steering wheel spokes when the wheel unwinds in the pits...)
BUT. Car has never seen street use.
Bought a B-body that had .850 bars in front, street-driven, LF was adjusted to the limit; my guess is street use killed it.
Hopefully you can extrapolate the above to be useful in your application.
