Here's why:
* Bellhousing: The bolt pattern on the Buick Turbo 350 transmission is different from the small block Chevy bellhousing. This means they are not compatible without modifications.
* Input shaft: The input shaft on a Buick Turbo 350 is also a different size and spline count than the small block Chevy engine.
To make a Buick Turbo 350 work with a small block Chevy, you would need to:
* Replace the Buick bellhousing: You would need to find a bellhousing specifically designed for a small block Chevy and then adapt it to the Buick transmission. This can involve custom machining or using specialized adapters.
* Modify the input shaft: The input shaft would need to be replaced with a Chevy-compatible shaft.
Important Note: This is a complex modification, and it's not recommended for someone without experience. If you're looking to swap a transmission, it's often easier and more reliable to choose a transmission that is compatible with your engine.
