VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1912-1928 Engine numbers

I have the same engine/cylinder head I.D. chart. I got it for $3 at Pro Antique Auto Parts in Windsor Locks Ct. about ten years ago.

I bought what was allegedly a 1921, but based on this information it is a 1927. The casting numbers are 346709 with F107. Applying the information from the previous posts, June 10, 1927. It has the following sequence of numbers stamped into the block 3468594, is that the serial number?

That number is in the sequence used for 1927 engines. First '27 engine was 2874999 and first '28 engine 3863596. Your number would put it approximately at a mid-June assembly date. That is consistent with casting to assembly time of a few days. Not like the reported aging of block and head castings by the four letter competition.

Thanks for the response, I appreciate the help.
