Fwd auto good for 450hp?

[4gst]

Just like the title says I'm at about 400 right now but planning to be at 450 or a little more and once my 5 spd tranny goes I want to give auto a shot. I want to know if it would be more reliable then a 5 speed at these power levels or what would I need for it to handle these levels? The car is only used for drag racing.
I did search but didn't find anything other than kiggly which is a 1g.
thanks in advanced.

I'm pretty sure the A/T would need to be modified to be able to take that 450hp. At stock form they are reliable up to 300hp. IPT is the only thing that comes to mind, they have translab shift kits and modified valve bodies to take the abuse all day. Performance torque converters is a must for 400hp and up. Good luck.
