Information provided here is provided solely to aid a potential owner in determining the heritage of their L78. An example 'suspect' car would be an L78 with proper paperwork but the history of the car shows it was a 'barn find' and the engine was long gone when the car was found. However, suddenly the car appears on the market with a restamped engine and is being sold as a 'matching numbers' car. The term 'matching numbers' means different things to different people but here it's used to mean the engine build date stamping and the partial VIN stamping on the block are original and have not been altered. A 'barn find' L78 with a missing engine has a 1-in-xxx chance of finding its original block depending on the year. You be the judge.

March 20, 2012: I wanted to inform you of the unfortunate destruction of a 1969 L78 Chevelle. I am doing this to keep the registry intact and pure. The vin on the very, very rusty car that was destroyed is 136379K416210. It was a 72/72 paint code black standard bench seat Chevelle SS. The car had an original single fuel line and it was also a non air conditioning car as would suggest an L78. I hate to see any of these cars destroyed but it will donate many parts to other deserving Chevelles. Please update your registry as necessary to prevent any potential retagging. - Courtesy Marc Campolieto
