How much does a 350 chevrolete engine weigh?

The weight of a 350 Chevrolet small-block engine varies depending on the specific year of manufacture, the components included (e.g., accessories like alternator, power steering pump, intake manifold), and the materials used. However, a general estimate for a bare, complete 350 Chevy small-block engine (meaning without accessories) is between 400 and 450 pounds. Adding accessories can easily add another 50-100 pounds.
