transmission?

[toothenator]

I wondering what route to take on the transmission for my truck. It's an 88 C1500 and I intend on putting a carbureted stroker motor in it around 400-450 hp. I have seen 700r4 transmissions for sale that claim to handle that kind of power but I worry that 500hp may be the upper limit and I would rather under stress my transmission than push it to the limit but I'd also like to keep the price of the tranny comperable to that of the 700r4.

Any ideas??
