K2 for the first 2 digits of the engine number would indicate the engine is a 1952 model year 288. The remaining 21665 is the sequence number that would give an indication on where in the total 52 production of 288's it was made. That number would end around 50000 so the engine was made maybe a quarter to a third of the way into the production schedule.
Was originally installed in a 200/200 Deluxe model and is probably 135 hp unless a different head was installed to up the compression ratio slightly. No easy way to tell if that happened. It will have 5 main bearings and if there is no other marks or letters such as an H stamped somewhere around the engine number it will have solid lifters. You can find all the other specs on the engine in the Packard 51-4 service manual or in the 52 model year introduction specs in Nov 15, 1951 Service Counselor.

That date would be the date the engine block was cast by the foundry. So no, not the manufacturing date of either the assembled motor or the vehicle it was installed in.

G'day PackRat,
![]() However if you reunite the engine/trans with a Packard body, don't forget the Registry.

Also, for 1951 through 1954 and maybe earlier all the heads were Thunderbolt except for the original aluminum head used on the 1954 359 engine. If you want to know exactly which head, then look at is casting number (near the water outlet) and see if it matches a part number in the parts book.
