Good morning everyone the question I have today is are the dimensions of an early 289 ford motor with a C-4 attached the same as a late 80's 5.0 motor with an A.O.D. attached the same. What I have is a stripped 289 block and a C-4 case attached and I want to use that as a mock up motor so that when I'm done I can drop in my 5.0 and A.O.D. that's all together this is going in a 55 ford fairlane with a fat man front end on it
