Yes you read that right Im doing the reverse of everyone else. My 86 Cutlass has a 403 with TH350 but the 350 is wasted and I just came across a good rear with Posi and 3.73 gears so its Overdrive time. The previous owner hacked up all the wiring, but Minion was nice enough to give me his old computer, wiring, and trans so Im back in the game. What should I need to get the trans working right in this car? I have the 200R4, torque converter, new shifter, new over lay for the console, the bracket for the cable to the carb, Im in the process of trackign down a CCC Carb and I have the Distributor. Tell me what you guys think.
