No, a 700R4 torque converter will not fit a Turbo 350 transmission. The two transmissions have different designs and mounting points, as well as different internal components. While they may seem similar, the torque converters are specifically designed to work with their respective transmissions, making them incompatible with each other. If you're looking to swap converters, you'll need one specifically designed for the Turbo 350.
No.
No it will not. Because it is a lock-up converter and the 350 turbo is not set up for a lock-up converter.
Everything I've heard, no they will not...
yes a 350 turbo converter will fit a 400 turbo and vice versa
Yes
No.
NO............
turbo 350 or 700r4 turbo 350 or 700r4
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.

not necessarily. depends on what it was made to do.
A turbo 350 has only 3 gears. The 700R4 has 3 gears plus over drive and lock-up converter. And it is the same as a 400 turbo with overdrive.
