1977 Jaguar XJ6

Additional Info:

This was my father's car who passed away. It has been sitting in his garage for at least 2.5 years. Selling the house and the car is the last item that needs to ago. It was running before he got sick, I think a mechanic messed with the carburetor some years ago and now it just sits. Been sitting now and no clue as to running status. Will need to be towed from location. Has always been garage stored. I do not believe the engine is original. Please see pictures for details. Millage unknown.
