I am looking to rebuild a 390 for use in a Cobra. I have two used engines available to me.
1) Casting D3TE, Date Code 4F23 Head Casting D2TEAA the engine has a 2bbl manifold on it and a flexplate, indicating auto. trans. The
oil pan is a front sump. From the date code, I come up with July, 74 which would indicate a truck engine?
2) Casting C?AE-A, Date Code 5A13 Head Casting C4AE the engine has a 4bbl manifold and a flex plate. The
oil pan is a front sump. The date converts to Jan, 65 , the engine comes from a 65 Thunderbird but we don't know its history.
Which, in your opinion, would be the better choice and why? What is the going price for a used 390 for rebuild?
Thanks for any help
Paul
