Engine ID Help Needed.
New to the hobby and need some help identifying the motor in my truck. It is a 1969 F250. The VIN tells me it should be a 360. The person I bought it from told me it has had a motor swapped, so who knows what it is. I bought Steve Christ's book on how to rebuild FE motors and the ID codes on my motors block were not listed. So I have no clue what motor this is. I finally found the numbers on the block above where the started mounted. In the book it said it should bew stamped on the front of the block. It wasn't and there was no tag either. The numbers are as follow: D4DE-6015-BA and below, I assume the date code?, of : 5M11
Any help or a kick in the right direction would be appreciated. I am going to attempt a rebuild so I need to know what I have.

You have a 1976 360 or 390. The long number is the engineering/part number. D4DE indicates an engine part released from engineering for production in 1974. 6015 is the generic part number (I assume for an engine block, though I've never seen a block with the full part number on it), and "BA" is the revision code. The first revision of a part is A, the second is B, and so forth. AA would be revision 27, so BA should be revision 53. I've never seen a BA revision code before, however.
5M11 looks like a date code. The first digit should be the year (1975), the second is the month, and the last two are the day of the month. M would be December (I was skipped), so your block was cast on December 11, 1975. It must be one of the very last FE blocks, as they went out of production sometime in early 1976.
As to whether it is a 360 or a 390, there's no way to tell without measuring the stroke. The 360 and 390 used the same block, heads, etc., and are externally absolutely identical.
