Can anyone tell me for sure if this number that is stamped on the passengers side of the block, in front of the motor mount and behind the alternator (upper left of this photo), is an identifying number for this individual block, or is this same number stamped on all LS3's?
Thanks,

Cant get a look at that location with motor installed. It's obscured by the head, and wiring harness/lines. Sorry, maybe someone else has a motor outside a car

Thanks for checking, I appreciate it.
Anyone else have one on a stand they can check for me?

Pretty sure the serial number is at the rear of the block on the right side. You have to view it from the top behind the passenger head.

The number is different on each block. Here is my LS3 block. However, this number is on the driver side of the block. Not passenger.
