I once owned a 1978 Dodge Polera ex-CHP car. I was a freaking blast to drive. Last year of the 440 hipo big block with a Carter Thermoquad four barrel carb.
It had a 140 MPH certified speedometer. Limited slip rear diff, giant swaybars front and rear, huge brakes, 3-row HD radiator, quick-ratio steering box. Giant HD alternator, "blue" neoprene radiator and heater hoses, dual exhaust and no cats!
It was built that way from the factory. Heavy duty police grade everything. It was built like a tank and drove like a sports car.
