  • 1988 LINCOLN
I purchased a used engine and was told it came out of a 1988 ford mustang.

None of the parts I ordered fit and the parts house believe the engine came out of a mercury marquis?

This number is stamped on the top of the block just behind the rear manifold. There is no number by the starter or anywhere else on the block.

Can you tell me anything about the engine by the number JY812095?
Do you
have the same problem?

Is there another number on the block by the freeze plug areas? This number looks like when it was made, like 8-12-95

Look on the sides. It should be where the freeze plugs are.
