What is Engine color for 1975 Chevy 350?

There's no single engine color for a 1975 Chevy 350 small-block. The color varied depending on the factory where it was assembled and even the specific date of production. Common colors during that era included:

* Light Blue: This is perhaps the most commonly associated color with GM small-block engines of that period.

* Dark Blue: A darker shade of blue was also used.

* Dark Green: Another possibility.

* Black: Some engines, particularly those for some applications or later in the model year, might have been black.

In short, you can't definitively say what color a 1975 Chevy 350 engine *should* be. Its current color is likely the result of repainting or simply the effects of age and weathering.
