I have a friend that bought a 98 v6 converted to a 00 4.6 gt motor. It's an automatic with a gt rear end (3:73)..It is supposed to be a 00 motor but how do I tell if it's 96-98? The car has zero mods but flowmasters. What should he do for mods? It is a daily driver but he wants it to perform it's best and handle well. Thanks
