I recently picked up a very clean 65 Coupe with a 289. The previous owner said he wasn't certain but thought it was the original drive train since it only had 42K miles on it. It needed some freshening up so I pulled it to go through it. In the meantime I threw a 302 in it just to keep it drive-able. After pulling the starter and looking at the ID I'm pretty certain this can't be from a 65. Here is a pic if anyone can confirm my suspicions. I believe it is a 67 block. It also has some blue paint under the poor black paint job. I don't think 65s had blue blocks. If its not is there any reason to bother rebuilding it to put back in the car? I now have a decent 302 in it. Any suggestions? I'm just venturing into classic Fords so I could use some help!!

Thanks. The date code 7D18 is my main concern. Doesn't that mean April 18 1967? Is it even possible this was the original motor from the car?
