I dont see anything that G-Forcesuspensions does that allow you to bolt in a leaf spring or four link housing... into a three link torque arm suspension ??
I will say that a few years ago, I used to build all of Duttweiler's differentials... and I dont think one of his (or his clients cars) ran slower than a 9.80. Most of them leaving on a brake as well... now talk about abusive impact loading. Thats about as bad as it gets...
The 8.5" is plenty strong. But, you gotta spend some money to get it to be that strong. I dont know what you consider "a ton of power"... but Duttweiler's normal detuned street builds were easily in the mid 800+ hp range... and even more so in track trim. Like well over 1k hp...

9.70 396"lt1,procharged,N2o,4L80E 8.5" rear good axles and 4.10s
9.60 @148 in an 87 GN weighing in at 3600lbs does not take a ton of power to do but i will tell you this much that rear end will hold up to some decent TQ.
theres many superstock guys using the very same rear,with a bunch of gear in them w/HD axles 5.13-6.14 etc with 1.4-1.6 60's.

South Side Machine has had a solid link rear suspension for years... but there are and always have been inhearent problems with a solid link suspension in an F-body. Even more so when the links in the G-Forcesuspension kit are that short...

Here's what it comes down to:
1. Is 8.5" stronger than 7.5" in all areas (digs, dumps, drifts)?
2. How much more does 8.5" weigh vs. 7.5" (unsprung weight concerns)?
3. Does the Traction Control and ABS hook up properly?
4. How large of a variety of Limited Slips, Lockers, etc. are available?

all my comments are about the 8.5"rear
from the start it was about the 74-81 8.5" rear ends from me.
GM kinda gave us the short end of the stick with putting the 7 5/8 rears in our cars for heavens sake they came in the vega,sunbird, monza,s10.THANKS BEAN COUNTERS!

8.5's came in limited numbers in 4.3/5speed s10's and the v8, boosted and or juiced v6 guys are putting down tons of power
one i can think off off the top of my head is pulling 1.6 60' from a 4 k clutch drop and running low 12's
there are also a ton of auto guys pulling 1.5's running well into the 10's wsith the 8.5

i'm thinking about doing it with a ladder bar setup. unless i can get the peice that bolts to the moser 9'' for the torque arm. i guess you would call it an adapter. but then i could just weld three tubes on the 8.5 and bolt that piece to it. i don't know wich way is better.
just keep in mind the 73 and older 10-bolt rear ends are NOT 8.5 they are the 8.2 rears that are a bit weaker,74-81 are the true 8.5 in the f-bodies,very few 86-88 wagons got the 8.5 similar to the GN.
the length is 61"so the use of aftermarket rims would be needed,3rd gens can have these rears bolted in and re-use the factory wheel
