Yes. Any engineering number version of 289 block casting mid 1963 model year through the end of 289 c.i.d. engine production years later could be selected, tested, and completed into a HP289 assembly. There was nothing special about the blocks other than being hand picked and verified to be suitable for High Performance 289 use.
The pictures shown in Post 35 are of a late 1963 (near the very end based on serial number and assembly date recorded elsewhere) model year HP289 production short block assembly.
