Can a police interceptor engine and transmission from a 2000-2003 Ford Crown Victoria be put in a 1978 Ford F-250 and if so what modifications are needed?

Answer 1

Everything about that engine and transmission are computer controlled, so you would have to incorperate the harness and computer system into the 78 truck, which had no computer. Also all 92 on up Ford vehicles use electronic speedometers which are powered off of the abs sensors, but the F-series for 91 and earlier used a cable driven speedometer that was driven off of the transmission, so you'd need to replace the speedometer. The F250's "Charge" meter is incompatible with the newer alternators Ford used since the late 80's, so I belive you'd have to make a custom gauge cluster or reuse a 2000-2003 police interecptor gauge cluster as they also have to idiot lights required for the ECM (engine computer).
