I have one of these blocks in my vette, but it is believed not to be original. It is a BB chevy, 427 CID. Does anybody know what vehicles used this block. I have seen 3916321, but never heard of 3816321.

Pretty sure it's a casting thing, the 9 is a 9, just not clearly cast. The bottom "hook" of the 9 is touching the top and giving you the look of an 8.

That's what I was hoping for. I have yet to be able to decifer the casting date. I'm going to try to lift of an impression of the casting date using clay. Wish me luck.

The blocks were used in all sorts of Chevrolet products. I have seen that block number for Chevelles. It is probably the same for trucks. Those engines were made in Tonawanda, just outside Buffalo, NY.
