Handling 400HP isn't really a problem. You won't get 100K out of it though. No matter what extent you go to building a 4L6X, it does not have enough total friction surface in the band or in the 3-4 clutch pack to last that long. Removing torque management is a popular programming modification - that probably takes 40% off the service life of the trans too.
Read some other threads. You will see those who have spent thousands on new fully-built performance 4L60-E or 4L65-E transmissions. You'll see how happy they seem to be with them. Read some more and look for those who went through this all long enough ago to have some real miles on one. I think you'll see a trend. Most of the been-there-done-that crowd have a very low opinion of these autos, myself certainly included.
