Squallie

Hello, yesterday my brother picked up a 1995 Mgm LX. he picked it up for $800 and it needed a battery and just some cosmetic love. this is his second one being he sold his 93 about 3 or 4 years ago. and the place we got it from has another Mgm and a brown crown vitctoria for sale. neither are driving because the Mgm is wrecked with a good interior and a good running motor. then brown crown vic has a bad motor and straight body ect. now that my brother has bought his white Mgm we want to buy these to junkers and swap the Mgm motor into the crown vic and as well as some interior parts. and then the wrecked Mgm comes with a digital dash and im giving that to my brother. may sound confusing but anyways.....what problems will i have swapping the motor from the wrecked Mgm into the crown vic? their both mid 90's cars and both have the 4.6L motor. is it a direct swap? or will i need to do something to it?
