350 Chevy 5.7lg what year and model is it?

A 350 cubic inch (5.7 liter) Chevy small-block engine wasn't specific to any single year or model. The 350 was a very popular engine produced by Chevrolet over many decades (from the late 1960s through the early 1990s in its most common form). To determine the year and model of a vehicle with that engine, you need more information, such as:

* The vehicle's VIN (Vehicle Identification Number): This is the most reliable way to identify the year, make, and model.

* Casting numbers on the engine block: These numbers can help date the engine's manufacture.

* Other engine markings: Look for any other markings or stamps on the engine itself.

Without additional information, it's impossible to determine the year and model of a vehicle equipped with a 350 Chevy small-block.
