A cast-in 12651168 denotes a LS6 block. There is another way but not too sure how accurate it is but there is a bulls eye located on the block on the passenger side just below the head if you have this I believe it’s a LS1 block if no bulls eye it's a LS6 block. Also the luster of the block is shinier if it is the LS1 and if dull (like sand blasted aluminum) it’s a LS6 block hope this helps.
