I have no idea what it is, I am looking for markings on the engine. I know it is a Ford V6 SHO. I don't know the year or if it's a 3L or 3.2L. The engine is seized up tighter than a drum. Rebuild? Or to replace, what do I look for to find out which SHO motor this is? Engine harness is completely removed from the motor, so I will need an electrical schematic, etc. I do not know what this motor is specifically though. Year, size etc. It has lots of components that are usable so I would like to find another identical motor to work with.
