I have a '95 Mustang with a 3.8 V-6 with a cracked head. Need to replace the engine, but have been told by many people that the '94 - '97 had problems with the heads. Now I believe it. lol I've got a question for anyone that might be able to help. If I were to put a '98 or newer 3.8 in it, what would have to be done to make it work.
