I purchased a 65 a code mustang and an extra motor came with it.I was told it was the original how can i tell? I
have the numbers off of the block they read c4oe-6015c and
it has flat top pistons.Any help would be greatly appreciated. thanks mark

Adjacent to the casting number is a build date code. The engine build date should precede the vehicle production by no more than approx 6 weeks (IIRC, correct me if I'm wrong). I may also be wrong, but I would think a 5-bolt bell would be either a C or D code engine and that the A-code would be a 6-bolt bell?

I don't see a C5AE-F listed
C5AE blocks were the first of the 6 bolt bell housing 289's
Are you saying that it is not the original engine/block??

(How do I post a pic? )
