Looking at Henry's blog his motor is stamped on the back 440275.

The service concealer vol 29, no 5, page 29 talks about engine numbers.

The Packard Service Technical Bulletin 55T - 33, dealer 24, dated July 14, 1955, is on service engines. The last paragraph talks about how to tell the difference of the engines by looking on the flywheel housing. Casting number 446521 is the 3-3/16" bore. Casting 440275 is the 4" bore.
