You've got to start somewhere...and the Corvette's storied racing history began with this '56 (and its similarly-optioned counterparts).
Think that's interesting? It is! So was writing about this historic C1 in 2009.
When you look up the feature story on this '56 Corvette SR (in the "Featured Corvettes" section of this website), you'll see the inter-Chevrolet memo that Zora Arkus-Duntov wrote that got the top brass' attention--and set the works in motion that resulted in the "SR" options in '56.
From that point on...you know the rest of the story. By the way, here's a run-down on what RPO's were SR way back when:
