I need help finding a ID number on my LS1 motor. Where is the ID # on a 2002 Camaro motor? :(

The casting number is located on the driver side rear, at the top edge of the block.

The number 1221022557 doesn't look right. It looks like all the blocks started with 125

Thanks Chevynut, your information was helpful. I found the number 12559378. I took this LS1 motor out of a 2002 Z28 Camaro. It had 4k miles, and been in storage till now.
The information says it's a 1999-2000. I guess they had a lot of extra's since they knew that it was the last year of those motors.

Here is the information I have on that casting number.

It is a 2000 Firebird/Camaro LS1 5.7L (346" cid) Cored rear cover oil passage, improved oil distribution and flow.
The powerplant was rated at 305 horsepower for this year. That is for the Firebird/Camaro.
