yes a 350 turbo converter will fit a 400 turbo and vice versa
Yes but do to the 400 Turbo Trans being much longer you will need a shorter drive shaft
There's only one type of 400 turbo.
No it will NOT interchange. The 350 and 400 turbo are actually VERY different transmissions.
no
The 350 turbo is a good transmission but the 400 turbo will take more abuse.
About 125 pounds
Every part that is in the 400 is heaver and bigger then the 350. The 350 turbo is light duty, but can be modified to make it tuff. The 400 is already tough from the factory.
Yes
