The 700 will fit, and has already been said the 4x4 takes a shorter output shaft. The case of the 700 is longer than the 350 so it takes a different adapter for the transfer. the one from the 350 will bolt on but the drive shafts won't fit and the output shaft will be to short to spline into the transfer. Call the local dealer and get the adapter from them. Ask for 1982 up 4x4 700R4 transfer adapter.
Also 86 is the last year that you can lock it up w/out electrical. This tranny can be locked up hydraulic.
Get the vette converter rebuilt, or one like it, they are around 2200/2400 as are. I use these, and my converter man furnace brazes them, and adds the late converter clutch.
