You can do anything with engine, just time and money. They are wider than big blocks, so you gotta have alot of room. If you check out the "Blacken" mustang, its a 69 with a 4.6 cobra engine in it, sweet indeed. If you check out some older issues of mustang and fords they go over the 4.6 pretty well, the current issue actually has the an article about the blacken mustang in it. Good luck
