What distributor comes with a 1975 Chevy block 350?

A 1975 Chevy 350 small-block engine didn't come with *one* specific distributor. The distributor used varied depending on several factors including the specific vehicle it was installed in (different vehicles might have different emission control systems), the engine's options (like the carburetor type), and even the production date within the model year. There wasn't a single, standardized distributor across all 350s produced that year.

To know the correct distributor, you would need to:

* Identify the vehicle: The make, model, and year will narrow down the possibilities significantly.

* Check the engine casting number: This number, usually found on the block itself, can help determine engine specifications and the associated distributor type.

* Look up the original specifications: Using the vehicle identification number (VIN) you can often find build sheets or factory records specifying the exact distributor used. Websites and resources dedicated to classic Chevy restoration are very helpful for this.

In short, there's no single answer. You need more information about the specific 350 engine to determine the original distributor.
