I have the motor for 8F91W8532653.
That is a fantastic score. Where did you locate it, was it in a car or sold by a private seller with or without a GTE ? It is also interesting to learn where in the country the motor was last sold.
Neat stuff and the person who has the car if it is still around would love to speak with you.
What are your plans for the engine?
Would like to reunite it to the car it came out of.
