Goal Mid-Low 13's?

Don't forget about suspension! With all that power that you'll be adding along with the 4.10's your going to need to harness what you got and put it to the ground.

I'd say forget about the C-4. Get a Lentech valve body, and a 3000 rpm stall converter for the AOD, and you'll be set. The Lentech valve body can be shifted manually and has an OD lockout option so you won't shift into OD at the track.

Also what about heads? That will really increase power over stock. If you add heads to your list, I'd say you might be able to get high 12's depending if your car can hook up like it should.
