I want to put an O/D trans in my car, but I don't know which is the best to use. I'm planning on 425 to 450 hp so the trans will need to be able to handle it. I was trying to avoid wiring computers in the car for electronics, but maybe that is the way I will need to go. Any suggestions or past experiences will be greatly appreciated.

While I agree Jake is the guy to ask, he doesn't do the 700r4 anymore. He has gone back to the 200R4 which is a much easier swap.

Im doing the 700R4 in mine. 3.73 gears in the back. I think you will be quite happy with one, but do the version that doesnt require the extra electronics.

if you go 4l80e you will have to spend some cash on electronics or have it full manual. a 700r4 or 200r4 will both make you happy. I ran a 700r4 behind my big block, 500 hp 600 tq, only changed to 4l80e when we doubled the power.
