Police Crown Vics are nothing special shoc 4.6 v8, AODE 4 speed auto transmission, 4 link live rear axle, same as a regular Crown Vic. Now the differences HD cooling (tranny and engine), HD altenator, HD suspension (higher rate springs, thicker f/r sway bars, HD gas shocks) Chassis reinforcements, Minor engine, transmission, and ecu mods worth maybe 20 hp total, shorter rear end gear, LSD, HD rims, HP tires varies summer winter that's pretty much it. Now keep in mind that police cars are heaiver than regular editions so right there you loose some of the advantages. If a regular marked crusier ran high 14's, low 15's I'd be very suprised. Now state cops, unmarked cops, and anything besides a crown vic can be a different story. And last but not least, YOU CANNOT OUTRUN A RADIO.
