It's with all accessories, but without the flywheelwith everything? where is the source?
I'm sure you know its based on the duratec v6. Maybe you could use a drawing of that engine?Next question, I guess is are the external dimensions, or drawings available?
If you are planning to replace a v8 with a v12 i just found this: Vanquish'd Pony project - 2005 Mustang - Western Motorsports
EDIT: I'll try to find a drawing later
