If you ever go to the Petersen Museum in Los Angeles, it is well worth paying a few extra bucks to take a tour of the vault. They have an original 57 Chevy “Black Widow” drag car that was in the vault when we went through a couple of years ago. The Black Widows were built by SEDCO with “back-door” funding from Chevrolet and this particular car was diverted from NASCAR to drag racing where it ran in G/Stock.
