engine number

[hawkhunter-2]

Can anyone tell me if engine number P78111 is a 259ci or a 289ci?
Thanks.

P usually denotes a 289, however in 55' the President 259's had a P prefix, but those engines ended at around #22,000. So you should have a 289...

Thanks Bob. We read the number wrong. It is P78911 if that makes a difference. The engine came out of a 1961 hawk but the owner had listed it first as a 259ci. We thought of putting it in our Packard Hawk until we rebuild original engine with the supercharger. My husband likes a 4 barrel and is not sure which way he wants to go with this car. It is a original 3-speed with OD.

Pat, if you haven't already, please also visit and put your hawk on the registry at the Packard Hawk site and forum: http://www.packardhawk.com/

It has some helpful info, more specific to PHawks. Technical stuff like your question above is more suited (will be answered quicker) for the SDC forum here.
