I had a 69 Block 4 bolt main, 3970010 Casting Number. I was going to use this block to build a 69 Z-28 302 Clone engine. It had the 010-020 cast numbers also with that strengthen 4 cast strips as shown in a picture about this topic. It had the correct 302 Cast Number caps too. It just was not a DZ stamped block. Hope we find out more info about these numbers.
