I stand corrected the last Casting of the 289 was C6AE meaning 1966 and probably sold out into 1967 ... and the 302 took production in late 67 and according to those the eariest casting numbers C8TE & C8OE was the first castings dated 1968
Denis obviously your example below is a stamped number which the only Ford Motor Stamped by Ford were the Boss 302 and 429 in the USA ... it seems maybe by LAW the stamped serial # motors seemed to be the import / export engines.
A casting and date code on a 289 block is up under the starter.
