I don't want to hurt fealings or step on toes but with his set-up IT WILL BREAK!
Any diff can break with enough abuse.
I speak from experience 3800lbs 69 Roadrunner with a 10" slick, 5 speed, Cal-Tracs, around 650lbs/ft torque. I have broke axles, bent things on a Dana 60. The 8 3/4 would have destoyed it self long, long ago. 
 I wouldn't recommend an 8-3/4 to anyone but everybody knows that. 
This has been discussed by you and I before Quicktree. I'm still using one in my 67 Belvedere running low 10s. It weighs at least 3750 lbs race ready. Leaving at approx. 2000 rpm. 1.42 60 ft so I'm not beating it at the hit.
Using Mark Williams axles, spool and Richmond gears.
Like the Everready Bunny...still going.
Happy Holidays!
what size and type of rear tire do you run?
9x28 Hoosier bias ply Slick or M/T 9x28 bias ply Slick
there you have it, I did the same thing with a small 9" slick many years ago. believe it or not you are not dead hooking with that tire, you get just enough slip to let the rear live. and yes you can still lift the front wheels and have a little slip. the combo works for you right now but put a 10.5 on it and watch it explode. been there done that going from a 9" to bigger tire. Monte was spot on....
Switching to the 10.5 tires next season. I'll let you know how I do.
Merry Christmas and Happy New Year!
