That's kind of a fuzzy engine photo but I see a GM air cleaner and can't seem to find a distributor. Oh look, the coil wire is running to the back of the engine. What this means is that either the engine shot is from another car for sale and was put here by mistake (that's what it looks like; look at the firewall) or this Mustang has a GM engine in it. The latter is bad news!
