1957 Chevy 150 For Sale

In late 1956 when the new 1957 Chevy’s were starting to show up at local dealers, a small branch of Chevrolet located in Atlanta called Southern Engineering Development Corporation or SEDCO began to build a series of sedans for America racetracks. These special sedans were built to challenge Chrysler and Ford racing teams.

Known in early 1957 as Duntov Chevy’s or simply Black and White’s they dominated A/Stock drag racing. When the NHRA created the Super Stock class for the Duntov Chevy’s and a few other factory built hot rods built by Ford and Chrysler, Chevy’s Black and Whites were then called Super Stock Chevy’s.

The term Black Widow was first applied to a few 1957 Chevy 150 black and whites that SEDCO built for NASCAR competition. The Super Stock Chevy term for NHRA SEDCO built cars soon gave way to the NASCAR term Black Widow for all the black and whites.
