If you have a 700r4 transmission in 1982 Chevy 4x4 blazer can change it with 350 or turbo straight across out having to anything else?
No, you cannot directly swap a 700R4 transmission in a 1982 Chevy 4x4 Blazer with a TH350 or Turbo 350 transmission without making other changes. The bolt patterns, output shaft configurations (for the transfer case), and even the bellhousing pattern might be different depending on the year and specific engine used. You'd need an adapter or to change various parts to make it work. A direct swap isn't possible.
