You can absolutely use a TH350 or TH400 behind the 250/292. They'll bolt right up! However, the TH400 uses up much more HP than the TH350 and the latter will be just fine, even behind the torque of a 292.
Also, stick with a 3.73 gear or so out back as a 3.08 will make the truck into a dog and your mileage won't increase unless you're using it 90% of the time on the highway.
