I have seen dates 5 14 69 and 5 28 69. I am trying to find when the blocks were cast, what dates. I was trying to find out how many were made. The numbers I found were between 300 to 500, but many were junked in machining. I read about the blocks being numbered on the rear and the main caps being numbered also. I got the matching number main caps with the block. I looked into buying this block after reading about the ZL1 cars, knowing that the low production of the blocks and costly price kept people from throwing them out after they were broke. As I said earlier it came out of a sprint car. When I asked about the broken pieces I was told they would be outside turn 2 at Port Royal Speedway. They last ran it about 1992 and it sat under the work bench. I saw it 6 years ago when I bought a set of factory heads from them. I figured it was beyond repair. I guess I am going to find out.
