Here's what you need to think about:
* Flexplate/Flywheel: You'll need the correct flexplate (or flywheel if you're using a non-standard setup) to mate the 305's crankshaft to the Turbo 400's input shaft. These are engine-specific, so make sure you get one designed for the 305 and the Turbo 400.
* Torque Converter: The torque converter is crucial. You need one sized appropriately for your 305's power output and intended application (street driving, racing, etc.). An improperly sized converter can lead to poor performance or transmission damage.
* Transmission Mount: A suitable transmission mount is necessary to properly secure the Turbo 400 to the vehicle's frame. This might require modifications depending on the year and model of your Chevy.
* Driveshaft: The driveshaft length will likely need to be adjusted to accommodate the Turbo 400's location. A custom driveshaft might be required.
* Shift Linkage/Controls: You'll need to adapt the shift linkage or install a new one to control the Turbo 400's shifting.
* Cooling: The Turbo 400 generates a lot of heat. Ensure you have adequate transmission cooling, potentially requiring an external transmission cooler.
In short, while it's mechanically possible, it's not a simple bolt-on affair. You'll need some mechanical knowledge and potentially the assistance of a professional transmission shop to ensure everything is properly installed and functioning correctly.
