You don't want that older Ford EFI crap. I have had two Crown Vics with it. Won't give you nothing but problems. Put an intake and carb on it. If you are going to use the stock heads remember to plug all the smog control ports in the rear of the head.Till you can get a better set of heads. The tranny on those if my memory is correct needs all that computer vacuum controls for the shifting. My cousin put one of those trannys in an older pick up and had to put a close hanger on the passing gear arm and move it as if it were being controlled by vacuum just to get it to shift even close. Real pain in the ass.
