Hmmm, I'm going to start recording some of the numbers on my engine and heads when I get a chance. Maybe I can get my butt over to my dad's shop and scope out my LQ9 longblock...it's supposed to be out of an 03 SS with 27K. I'll have to keep this thread in mind or make up a quick cheat sheet...
That's what prompted me to look, I was verifying that my motor was an '04 so I knew what headbolts to buy. It's a good way to verify what the seller is trying to sell you and what you KNOW about it. So jim bob redneck tries to sell you a 20K mile 6L out of a 2006 2500 truck, you look at the date code and clearly can tell it's an 02 block. You know it's not Kosher.
