There should be a number, digitally etched onto a pad down along the pad rail, I believe on the pass. side of the block. A long time ago, I was able to track that number I found on a block to the fact it came from a truck. This was back in about 04-05 and I can't even begin to remember how I went about tracking it. Isa ***** gettin' old.
Look for that number, if not the one you already have, and find a good Chrysler parts counterman. I'll be he could help tell you what it's from. For that matter, why do you need to know? It's either a variable cam block (09 up) or not variable cam (08 down). Other than that, they're the same between the cars and trucks...

The etched in number is most likely the engine plant information - (It came from Mexico).
They also stamp the vehicle VIN number on the engine, that will help determine what assy plant it came out of, which can help narrow down what car/truck it came in....

The only (variable) number I found that could be the VIN or partial VIN was the lazer(?) etched number. I think I used that number to track it. Don't remember now if I used it through the dealer I use or through some other contacts/systems. It was an LQK engine that I had enquired about and they jumped the gun and sent it out on a delivery truck, so I was able to get that info before I declined the delivery.
I remember tracking it all the way back to the insurance company who verified the truck had crashed down into a ravine. I later set my sights on getting a brand new engine...
Thanks for the help but all are NOT the same,The early truck blocks had thicker walls hence more overbore is available,I got it from a family in Indiana in a estate sale,The owner was killed when a jack let loose and crushed him underneath,Just want to know what I got that's all,It's funny you find out anything you want about "LA" blocks but the new stuff can be a mystery--"Anything that's not a mystery is just guesswork" thanks again Steve

While 5.7L blocks might on average have thicker walls than 6.1L blocks and earlier 5.7L blocks might on average be thicker still. I really think that the only way to know for sure is to sonic check the block. There was this belief that B and RB blocks from certain dates had thicker walls. Someone finally sonic checked a bunch of blocks and found little to no relationship between date of manufacture and cylinder wall thickness.

Where did you get your information from, internet rumors, Chrysler literature, a comparison by one of the 3-4 premium G3 Hemi builders? The only way I would believe they are different would be if the info came from one of the latter two.
I DO have Chrysler literature that states the 6.1 block is beefed up internally over the 5.7 block. That's the type of info I take seriously. For that matter, I've never seen anything that states the 5.7 block has thicker cyl. walls than a 6.1. The 6.1 has a bigger bore, but I've never seen anything legit that states they started out the same thickness before boring.
Whatever...
