8.8 or 9"?

I'm building up my 82 gt for street/strip should I put an 8.8 or a 9" under it?

You can build an 8.8 pretty strong. Unless you plan on getting super serious then the 9" will be just unwanted extra weight and work because I think are wider. I'm assuming your not getting that serious since you plan on still stretting it.

unless your building a dump truck or a full on 1/4 mile car that's tubbed etc then an 8.8 with the usual upgrades should be more then enough

You can run 10s with an 8.8.
The 9" will limit tire size. You will have to trim the axle tubes down. When you run wider tires you don't want them to stick out or they will rub the fenders. You can fit a 10" tire on a 10" rim with about 6" of back spacing on an 8.8. I would just get 31 spline axles and a locking differential and you will be good to go. Check out strange engineering. They have good axle stuff at a good price.
I would also weld the axle tubes to the pumpkin. I plan on doing this along with my special fabricated diff cover. I am gonna run axle tube supports off my diff cover. I already fabbed the cover. When it gets nice out will finish the tube supports. Here some pics of my cover and a pic of what I'm trying to replicate. My rear should be bullet proof when done. Btw you can purchase this setup for a but less than 300$.

most wont ever need the strength a 9" can give, build up the 8.8 and you will be fine unless you REALLY REALLY plan to run some fast times
