I had a 1983 Crown Victoria LTD. 351 Cleveland, Venturi Variable Carboratur, and former highway Interceptor for the Virginia State Police. This car had about 120,000 miles on it when I bought it for $1,000 in 1992. Reliable as hell and fast. The speedometer read 140, I only got it up to 120 and it was smooth as butter even at that speed. No vibrations, no stress. Great car, wish I would have kept it. That engine was a champ. If I ever am in a position and can find another 351 Cleveland in decent shape I am buying it.
