I currently own a 1992 Chevrolet Caprice that was a retired Police drug enforcement car. It has around 179,000 miles but runs extremely smooth overall. I heard some peers throwing around terms such as, “Police Enforcer engine” and how it was “balanced and blue printed”. After a time consuming online search I’ve came up with virtually no information on this topic, so I was hoping someone could enlighten me as to what these terms mean and with the difference between for example a 3.5, 5.0, 5.7 liter engine is? Thanks much.
