Decode engine block numbers? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

87Bob · 12-16-2007, 09:22 AM

I have a block I am trying to confirm a decode on it can any one help? It is a four bolt main block 350 and it has the following stamped numbers:

F0413CKB & 12S253152

I get this from the books I can find:

F=Flint
04=April
13=13th day of month
C=?
K=?
B=?

1=Chevrolet
2=1972
S=St. Louis
253152=The VIN number

The CKB code decodes as 1972 350CID 165HP 2BBl going into an AB car line. The "S" decodes as a St. Louis built car which as I understand it was only the Corvette plant which built only 350 4 barrel engines. So what am I missing?

it is going to be interesting I'm planning on using it as a base for a 383 with about 425 horses.

Any 350 block will do that with ease.
