400 with 208 fit 86 blazer with 700r4 &208

[Alaska442]

Hello. I'm new here and just getting into building a k5 blazer. I have an 86 blazer k5 with 305 and 700r4. Trans. Case is a 208. Trans is blown. I found an 84 suburban with a turbo 400 and 208 case. What would I need to do if I install the turbo 400 and 208 in my blazer. Thanks.

It should all bolt right in. At that point in time, GM had started changing adapter lengths to make the overall length the same for different combos. 700r4/208, th400/208, and sm465/208 all share the same overall length.
