I don't think the Hemi made it into too many police cars, the price alone would put it out of most budgets I would think. It may have made its way into a few, especially the first generation motor. Also the Hemi was notoriously hard to keep in tune on a street/strip car, so I am sure the daily mileage and wear and tear in a police car would have made it a mechanics nightmare! The 440 was almost as strong of a motor, and a much more reliable package for everyday use.
