Not too sure where to put this so I'll post it here. I have a 304 in my garage that I have disassembled. I am wondering where or if the block is stamped with a production year, or if there is some sort of code on the block as to what year it was produced. Any help would be greatly appreciated. I need to start ordering parts and need to know the year. Or do I? Does it matter when I go to order heads, intake, cam, etc. for it?
