My Bad yes Lynch rd.3341 is the Lynch Road, MI. plant.
Take a picture of the engine pad stamping in front of the intake. (Red arrow) Or write down what you see there. (Numbers, Letters)
The 318 was the standard engine for your car. Nothing stamped under the AB means standard engine.

I think this engine is a 440. Not original.
Any idea on value?
I'm thinking about selling this one.
