1966 Dodge Dart GT Convertible

Does it have a motor/transmission and if so, what are they? Original to the car? If none, by the VIN was it a slant or 273? Do you have the fender tag and build sheet?
I believe I do have a fender tag there's no build sheet there's no motor or trans it has a six-cylinder centerlink in it so I'm assuming it was a 6 cylinder it does come with a left rear replacement floor pan Factory original and the other question just say yes thank you
