* Crossmember: The 700R4's case is longer than the TH350 or Powerglide that likely came in your Nova, requiring a custom crossmember or significant modification to the existing one.
* Driveshaft: The output shaft length will be different, necessitating a new driveshaft or shortening the existing one.
* TV Cable: The 700R4 uses a throttle valve (TV) cable for proper shifting, which needs to be correctly routed and adjusted. This is crucial for proper transmission function and longevity.
* Electrical: While not overly complex, the 700R4 may require some electrical wiring adjustments depending on your specific setup. A lockup torque converter necessitates a dedicated wiring circuit.
* Cooling Lines: The transmission cooler lines will likely need to be modified or replaced.
In short, while doable, it's not a simple swap and requires mechanical aptitude and some fabrication skills or the expense of professional installation. You'll need to source the appropriate crossmember, driveshaft, TV cable bracket, and potentially other related parts. Consider consulting with experienced transmission specialists or Nova enthusiasts before starting the project.
