* Bolt Pattern: The Chevy 305 has a different bolt pattern on the bellhousing than the 2.8-liter engine. This means the transmission won't physically align with the engine.
* Input Shaft: The input shaft of the 2.8-liter transmission is designed for the smaller engine, and it won't match the size and configuration needed for the 305.
What you need to do:
To make this swap work, you'll need to use an adapter plate and possibly a new input shaft. This is a complex project that requires expertise and specialized parts.
Here are some things to consider:
* Cost: Adapters, custom machining, and potential transmission modifications can be expensive.
* Difficulty: This is a challenging project that requires significant mechanical knowledge.
* Compatibility: Make sure the transmission is compatible with the 305 in terms of torque capacity and gearing.
Alternatives:
Instead of trying to adapt the 2.8-liter transmission, you might consider:
* Finding a 305-compatible transmission: Search for a transmission that was originally designed for the 305 engine.
* Swapping the entire drivetrain: Consider using a different engine and transmission combination that is already compatible.
Before undertaking this project, consult with a qualified mechanic or transmission specialist to ensure the best outcome.
