Auto or Manual Trans for FI LS2?

[4mm]

I am in the process of securing a low compression all forged LS2 that will be receiving a blower. The engine should have around 720-800hp at the crank and will be going into a Chevelle. With that kind of power output, I would tend to believe an auto trans would be best and more fun. What do you guys think? Auto or manual? Would I be limited to a 4L80e with that kind of power? The only drawback I see is the power it needs to get going. Let me know your thoughts..
