Which tranny should I go with?

[84_GT350]

I'm in the process of planning a motor/tranny/suspension swap for my car and I can't decide on a tranny. It needs to be able to handle about 700hp or so. The ONLY other stipulation is that it needs to be 100% automatic. Manual/auto might be acceptable just so long as I can put it in D and drive it normally. Do I wanna go with a Lentech AOD or a PA C4? The motor will be a 389ci stroker with DFI and a small nitrous shot on it. It will also be a 99.99999% street car. The tranny will be backed up by a 9" or an 8.8" with 9" ends and a T/A and PHB. I could live without the AODs OD gear but the C4 would have to be fully auto. Anybody? Oh yeah...I'm planning on either 3.55 or 3.27 gears. I'd like to be able to leave stoplights without melting tires.

So I pushed it up to 110,
That flathead motor was about to give in,
