Default Engine Identification help

I have the potential of getting a Corvette engine for a have the potential of getting a Corvette engine for a 1957 fuel injection. The numbers are:
Engine Casting-3731548
Deck- F927EL
Distributor- 1110905 7A17

Default Casting Date Found

The final number I needed is the casting date which is I276. If I understand correctly how to decode this the I stands for the ninth month of the year the 27th is the date and the sixth is the year thus the engine casting date is September 27, 1956. That matches the block date of September 29, 1956 in my best estimation of the build date is around October 10 based on the Vin number. Is there anything I’m missing?

This is obviously a rebuilt motor or at least cosmetically redone. You should post a picture of the engine pad where you got the engine code from. As mentioned just having numbers on it does not guarantee they are GM/UAW work.
