IMHO 8 3/4" is the way to go. Lighter than the Dana, but able to take as much punishment as you will likely ever throw at it with a small block. But beware, it is not QUITE the "bolt in" many claim it to be. You have to shorten your drive shaft, and the shock, and none of the axle mounting hardware (U-bolts, etc. interchange) Since you have the old ball and trunion trans, you will likely want to upgrade that too, the results being a drive shaft that is almost completely fabricated, so choose your drive shaft shop well.
