700-r4

okay, here's the deal. i have a 700-r4 now that needs rebuilding and can't handle the power that i have. I'm guessing im in the 400-450 hp range now and willl be running mroe boost and power soon. want to be around 550hp. anyway, I have a few problems:
1- i don't want to run a manual
2- i would like to stay with a 700-r4 or something else that i can swap right in wthout a differnt torque arm, etc.
3- i don't want to rely on a tv cable for line pressure, since i have a vortech carb enclosure, maybe I can get the geometry right but i can't locate the tv cable where it needs to be

So my delema is:
I can go with a 700-r4 with constant line pressure, but i heard that is hard on the front pump, OR i can go with a diffrent tranny, but i want to have an easy sway and i kinda would like overdrive.


also, i am non computer controlled now, but i do want my factory odo speed gauges to work.
