Will a turbo 400 bolt from a 350 to a 305?

Yes, a Turbo 400 transmission can be bolted to a 305 engine, as both are part of the General Motors small block family. However, you will need to ensure that the necessary adapters or modifications are made for proper fitment, especially concerning the torque converter and flexplate compatibility. It's also important to consider the transmission's input shaft length and the overall alignment with the engine mounts.
