What is the weight of caprice engine 1990?

There's no single answer to the weight of a 1990 Caprice engine. The weight varied depending on the specific engine installed. The 1990 Chevrolet Caprice offered several engine options, including:

* 2.8L V6: This would be the lightest.

* 5.0L V8: This was a common and moderately heavy option.

* 5.7L V8: This was a larger and heavier engine.

Without knowing the exact engine code (found on the engine itself), it's impossible to give a precise weight. You'd need to find the engine's specifications in a repair manual or online database specific to that engine code to determine its weight.
