Looking for help determining what 6.2 I have.

So I recently picked up a 6.2 (I was told ls3) from a friend. Story to it goes it came out of a 2012 Vette with under 4k miles. I ran the number on the back of the block 12621766 and everything I can find says its a 09 or newer LS9. They were in the ZR1's with dished pistons I believe? The pistons on this motor have valve reliefs but no dish. The casting number on the heads are 823. Anyone know where I can look to determine what I have? Any advice is appreciated.
