i have an 82 z28 with cfi. im thinking about tossing that garbage th200c and either replacing it with a th350 or a 700r4. any suggestions? and what mods do i need to make in order to do it. tv cable, speedo cable, drive shaft.

 

speedo cable should fit either, cross member should be fine for the 700r4 maybe the DS too, the 350 will for sure need a cross member and DS

TV cable is required for the 700r4, is the 200 not TV controlled? the 350 is a mecahnical bracket iirc

also keep in mind if going to the 700r4, to make sure the TV system functions correct the correct carb bracket/s may be required as well

 

Just put a 700r4 in my 82. Had to shorten driveshaft 3" and relocate crossmember. took some work but wasnt too bad. I marked bolt hole locations on cross rails with a sharpie and drilled holes slightly bigger than bolt. I then welded nuts to 3/16 steel plates about 2" square (these also need a hole drilled in them). I then welded these to the inside of the frame rails making sure everything lined up.
