8.75 or Dana 60?

Depends on how hard you are going to hit it.

Big tire, heavy car, trans brake/4 speed = Dana

8.75's can take some hardcore street action.

If you are frugal, you can build a spooled Dana for under $1000. I just bought a strange spooled/axled 4.88 Dana shortened to 50.5" for $850. You can find decent deals.

If you are starting from scratch, I wouldn't waste my time on a 8.75. It will cost the same to outfit as a Dana once you get done.
