I bought my truck with 80k on the clock, and installed a tranny at 126k, so not that long ago. However, I installed a drag comp and gauges the night I brought the truck home, and within 4 months and 10k I had injectors and a fuel system on as well. So it ended up lasting me pretty well, because it wasn't even completely dead when I switched. However, with all of that said, A friend of mine who's truck doesn't seem to be putting out as much power as me smoked his trans in about 5 months total. It really depend a lot on how you drive it. I'd say with a fueling box on it, with the wire tapped, you will be asking for trouble if you use the power you have.
100hp over, is enough to wear things out. 350RWHP will definitely smoke it.
