Not Ranked
Not wanting to throw a towel in the ring . . .
It should be mentioned that there were a few (about 1000) cross-drilled 390 Taxi and Police Interceptor engines produced by Ford about the time that the 406 and 427 were emerging on the scene. The 390 cross-drilled block was a center oiler, although the block casting had provisions for side-oiling, just never drilled at the plant.
Check the bore!!! is it 4.250" if not, and if it's 4.050, it's a 390, albeit very rare.
