Help needed decoding two numbers

Help needed decoding a 308  serial number 7300031 and a Hydramatic Trans H51-26174

The transmission is a 1951 Vintage Hydramatic built and installed in a 1951 Hudson.  The engine number has too many digits ... the"7" does not belong in a 308 Serial number.  The engine decoder sheet appears on my website ... thanks to Fred Pinder.

The block casting number is 310111 which per the website you provided (thanks), is a 1954 block.
The number 7300031 is stamped in the usual vin location on the block. The Butler book appears to have it as a 1954 model 7D  which began with 7269066 and up, but I was also curious about the 00031 digits and what they represent.

Pic attached best angle I could get.

Maybe it is just me, but I can not read the numbers in the picture you attached.

It's upside down due to it being in a tough place in storage. It is 7300031
