How much does a 4.0L Ford engine weigh?

The weight of a 4.0L Ford engine varies depending on the specific engine (there have been several 4.0L engines produced by Ford over the years) and what's included (e.g., accessories like the alternator, starter, etc.). There's no single definitive answer.

You'll need to specify the *exact* engine code (found on the engine itself) to get a precise weight. Even then, finding that precise weight might be difficult as that information isn't always readily available publicly.

However, you can expect a 4.0L Ford engine to weigh somewhere in the range of 400-500 pounds, but this is a rough estimate.
