This Casting number is usually found at the rear of the block on the left or drivers side on top of the bellhousing flange.

The block casting number on smallblock and big block Chevy V-8 motors is located on a ledge found at the rear of the block, most often on the driver's side. This ledge is below the deck of the block and the ledge forms the mating surface between the block.
Decoding the ID numbers on Chevy Smallblock motors: (Info compiled Ray Buck ) Since there are several numbers on the block, we need to identify the ones we're gonna use. The first one I usually use is the block casting number which is located at the back of the driver's side cylinder head and will look something like: 3970010. The block's casting number is generally located on the driver side of the block at the rear where the bellhousing bolts to the block. It's generally thought that the letters 'P' and 'T' represent 'Passenger' and 'Truck' but there's no evidence of this as of yet. 1964-1965 327 block casting number 3782870. 1964-1966 283 block casting number 3849852. The identification number contains a combination of numbers and letters and is seven or eight characters. The prefix explains the location as well as the date of the Chevy engine's manufacture. For example, a Chevy engine with the identification number S1029CTY was manufactured in Saginaw (S) on September (10) the 29th (29).
