This is where you need to recheck your information. MustangTek is a
good site but they list C3OE-6015-B as both a 260 and 289 block which can
not be. There are errors on that site. A better reference is Bob Mannel's
book; Mustang and Ford Small Block V8 1962 - 1969.
C3OE-6015-B is a 260 block
260 block are not marked with 260 anywhere, they are blank.
C3AE-6015-N is the first 289 block; casting started in Dec 1962
All 289 block have 289 cast into the valley, intake manifold and the heads.
Ford had to cast those numbers into the parts so everyone knew what parts
they had in front of them. Ford had 3 different block in production for the
1963 model year; the 221, 260 and the 289.
Most parts are a direct bolt on from 260 and 289 but there are a number of
little differences with some parts that you need to be careful of and you
have realize before installing.

I'm am no expert on the block issue, come to think of it, I'm no expert. If
you check MustangTek you will see that the 289 block was started in 1963
(C3OE-6015-B), 4.0 bore. I have one stashed in the garage.. The machinist
believes it has never been bored. These of course are three freeze plug
blocks
There is a gray area when it comes to date specific castings. I know some
savy Ford guys and they only hazard a guess concerning the blocks. Also
Ford didn't start casting the numbers 289 in the valley of the engine
until??????????? '65,'66?
Were there some 289's thrown into the mix when shipped to the U.K.......who
knows. All the parts bolt up to one another.......right?
