Installed 1996 Explorer 5.0 GT40 V-8 in a 1991 Crown Vic and the speed density system doesn't like this at all!!! Is there an easy and cheap way to convert this car and it's new engine to mass air? I've found tons of information on converting a Mustang to mass air but info. on doing this with a Crown Vic doesn't seem to exist.:mad2: Can anybody help!!!!!
