I didnt read through all four pages but its a useless swap...03 crown vic..we all crown vic motor is a 4.6 2v and makes no more than 230hp. Your v6 can make that with mods. if you are going to do a v8 swap then get the v8 thats supposed to be in there...the 4.6 3v. Unless the car is under 3k bucks and in awesome shape its still not worth it. You will need engine, harness,guage cluster,ecu,fuel system, rear end, complete front accersory drive and not to mention the a/c system if you want it...drive shaft and transmission. Also a 32v 5.4 will fit with no problem with proper mounts and k member...been done MANY times.
