* Bolt Pattern: The bolt pattern on the flexplate for a big block engine is different from the bolt pattern on a Turbo 350 transmission. They are not compatible.
* Torque Converter: The torque converter for a 400 Hydromatic is also different from the torque converter for a Turbo 350. The 400 Hydromatic uses a larger torque converter to handle the higher torque output of a big block engine.
* Input Shaft Length: The input shaft on a Turbo 350 is shorter than the input shaft on a 400 Hydromatic. This means that the Turbo 350 won't be able to properly engage with the torque converter.
What you need to do:
1. Flexplate: You will need to replace the flexplate with one designed for a Turbo 350.
2. Torque Converter: You will also need to replace the torque converter with one that is designed for a Turbo 350.
3. Input Shaft: Depending on the specific Turbo 350 you have, you might need to replace the input shaft with a longer one.
Important Note: It is highly recommended to consult with a professional transmission shop or mechanic to ensure proper compatibility and installation before attempting any modifications. They can help you determine the correct parts and ensure a safe and reliable setup.
