During the 1992-2003 5.2/5.9 Magnum V8 era
was there a “police vehicle package” from the factory.

Around the year 1998 Evans Cooling had an article on their website that my fuzzy memory recalls as involving Detroit Police Magnum 5.2 V8 Jeeps that tried out Evans Cooling NPG waterless coolant, including describing how the Magnum 5.2 head gaskets had to have enlarged holes near cylinders #7 and #8.

I do not know whether these engines were plain factory Magnums 5.2s or had some police modifications.

During that era I remember seeing some Ram Pickups with Police paint jobs.
