what is the difference between the explorer 5.0 and the mustang 5.0? i know the heads and intake are better on the explorer (gt40) but what else is different? the cam is prob diff.. would just swapping an explorer engine and changing the cam be the same and taking the heads and intake off? cuz i could buy an explorer 5.0 pretty cheap i was just trying to figure it all out. ive been looking and cant really find anything... thanx guys oh and sry if this is a newb question lol
