Block casting number

[Jason96R]

A friend of mine has found a block which he is told is a 383, but he is not sure and lives 500 miles to me. The date on the block is 3/28/68 and the number he gave me is 246813012LL. Any help you could give me is much appreciated.

2468130 is a 1959-1971 383 block

What does the 12 and the LL stand for?
