The best torque converter is one that is custom built to suit the intended application.
No it will not. Because it is a lock-up converter and the 350 turbo is not set up for a lock-up converter.
yes
yes
If you're talking about a TH400 transmission, yes... the TH350 torque converter is one inch smaller in diameter than the TH400 torque converter (12" vs 13"), and you'll have to make sure the holes on the flexplate line up (or drill them for both patterns). You'll get a bit more stall out of the 350 converter. If you're talking about the 700R4, the answer is going to be no.... that uses a lockup converter, which will not interchange with the TH converter.
yes a 350 turbo converter will fit a 400 turbo and vice versa
