 The 4.9 L V8 saw major changes, with the carburetor replaced by throttle-body "electronic central fuel injection".In contrast to competitors from General Motors and Chrysler, the LTD Crown Victoria was sold exclusively with a V8 engine.As the LTD Crown Victoria became a stand-alone model line for the 1983 model year, the 4.2 L V8 was discontinued altogether, leaving the 5.0 V8 the only engine available on American models with a 5.8 carburetor V8 engine also available, but only on fleet-usage models, particularly police cars, (in Canada however, the 5.8L remained available as an option on civilian models until 1991).
