9J28 is the date code of 69/Sept/28th. It may have 2 dots under the 9 as stated. There were no more service 427 blocks made in 79. Those were not made after 73. Service replacement or over the counter block as after 68 there were no more 427 production vehicles. 68 Cougar GTE was the last one with the 427.
