At my highschools auto shop we were recently donated a 4.6 H.O. Auto drivetrain out of an '05 Ford cop car. I understand that it's the same as the mustang motor. Its also brand new, so of course something crazy has to happen with it. We were also donated a 280z in great condition with a leaking fuel injector.
Thus the wheels started turning. As anyone done this and is it even possible? we're waiting on the car to be delivered so no measurements can be done. I do know that our 4.6 is 4 inches wider than a 289.
