I have a engine with numbers 327773 111521 H4P-9 any information would help. It is locked up has fly wheel clutch water pump.Taking it trany, starter, fenders and etc to Auburn Ca. chevy swap meet sunday.

1922c; 1924 Cylinder Blocks as used in either U.S. or Canadian motors used a Block Casting Code of #327773 and Head Casting Code of # 327772 until the end of Superior Series F, H and Canadian “SM” prefixed motors.

The block cast number 11-15-21 is the block casting date which is for the 1922 model 490. The H4P-9 is the casting mark of the Holmes Foundry Co. in Port Huron - with the #9 being the change level. The engine serial # is on the whee.

Thanks for the information, the Auburn Ca. swapmeet was a good one.
