Help me build my rear end!!!

Ok, stop laughing and if you tell a joke it has to be funny, .

I'm building a new 12 bolt for the 68 S/C truck 631TQ/622HP....(I know, I know I should probably go with a 9"....). It's going to have discs, a new posi, new axles and new gears. It's main use will be short trips to work and an occassional trip to our local 1/8th mile track.

Here's what I've come up with:

Auburn Pro
4.56 gears
Moser axles

Here's the dyno sheet for the motor and link to the engine thread. Thoughts or concerns?
