What is the weight of a gm 2.8 liter V6 engine?

There's no single answer to the weight of a GM 2.8L V6 engine. The weight varies depending on the specific engine model (different years and applications have different components and materials), the accessories included (alternator, A/C compressor, etc.), and the fluids within the engine.

You'll find a range of weights reported online, often between 350 and 450 pounds (159 and 204 kg). To find a more precise weight, you would need to specify the exact year, model, and application of the engine (e.g., "1996 GM 2.8L V6 from a Chevrolet S10"). Even then, variations are possible.
