Motor identification

[vso737]

Can anyone tell me what these numbers indicate:

BLOCK CASTING NUMBER- 3614230-4

DATE STAMP BY THE STARTER- 17782 A

ENGINE ID#, RH ABOVE OIL PAN- 2C208217

CASTING DATE, RH MIDDLE OF BLOCK ABOVE OIL PAN- " D N "

My understanding is that this is a 400CID motor built in 1972 at the Jefferson, Michigan plant.

The sequential VIN# is 208217

I do NOT know what the " D N " designates nor the date stamping by the starter.

Finally finished .................

Pictures attached.

Thank you in advance,
LG,
Mike

D- Dayturn
N-Night turn shift

D- Dayturn
N-Night turn shift

Sounds GOOD to me, BUT both the D and the N casted in the block.

I thought the stamped number by the starter was suppose to be the date the motor was put together.

Thanks for the input..............

yes the D and N are both cast, but it loos to me that there is an arrow pointing to the D, which means your block was made on Daylight.

You are 100% CORRECT. I need to pay MORE attention to detail....................LOL

Can you tell me what the STAMP NUMBERS by the starter reveal. I'm pretty sure it is suppose to be the date, hence, stamped and not a casting number. I figure the " A " stood for day shift................

Thanks again for all the help,
LG,
Mike
