Good luck. Ford was miserable about putting codes on FE engines. I've seen them with nothing but the date. You're looking for a C8AE-A, but that covers 68-76. Start looking for the date. Does it have heads?
I have not seen it yet, but it's supposed to be complete. I have to call the seller today to get more info on it. I know it's not a '67 and won't be #'s matching, but if it's compete and really a 4V I could live with it as long as the price is right. I am not going for a concourse restoration anyway. I will see if I can get the casting #'s from him and post them here for advice.
Thanks for all the help so far on all of my questions.
