not necessarily. depends on what it was made to do.
no
yes a 350 turbo converter will fit a 400 turbo and vice versa
Yes
No.
No.
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.
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.

Everything I've heard, no they will not...
Yes, the Turbo 400 will bolt up to the 305. Use the original Turbo 400 torque converter and flex plate unless the 305 flex plate has dual bolt pattern to except the 400 converter.
with torque converter and no transfer case (2wd) about 125 lbs.
