Mike....Although you are correct stating the VIN's were supposed to be stamped on all engines by federal law, many were not. Human beings were responsible for this operation and occasionally missed this important step on the assembly line. I've personally seen quite a few blocks with the Tonawanda stamping on the pad and no Vin in either location. The 12/08/69 built 70 L78 car was verified by the original owner as never having it's original block replaced, yet had NO VIN anywhere on the block. I personally restored this 55,000 original mile car in 1998 and can tell you it was definitely a numbers matching car that had never been restored or altered. All castings were Sept 69. The car is available for anyone to inspect if your interested. In addition to this, Mark Meekins (mrz16) recently advertised a LS6 512 block on ebay that had NO vin, even though the Tonawanda numbers were present. "70 SS 454 LS6 CRR Engine" T0522CRR. (Ebay item# 2446538909) This is not the first I've seen.......Kevin
