Not Ranked
I don't think Ford made the 260 in '65... that was done with in '64 when the 5-bolt block ended. The 260 has a 3.8" bore, so you have a 289, with 4" bore, and the engineering number for the 260 is C3OE-6015 E, whereas the '64 289 is C4OE-6015 E or C4AE-6015 E. The hipo motors use the same blocks, thus the same numbers, but the main caps are different.
