My buddy is thinking about getting a retired Police Cruiser when he finally gets rid of his truck. He's convinced that the come with Cobra engines. Now I'm sure they are moddified to an extent. But I highly doubt they come with the 4V Cobra engine. But just out of curiosity, what are the performance differences between a stock, factory Crown Vic and a Police Interceptor? What mods? Any HP/TQ numbers? Thanks for the info guys.
