Looks like the famous Don Yenko (post #76) has escaped detection. Here he is limping his '63 back to the pits at Sebring in 1965....

The following video is a brief history of Yenko Racing, Yenko Chevrolet and Yenko Specials. In the video, a reference is made to swapping in 427 blocks to Camaros, Chevelles, etc. General Motors had a 400 c.i. limit on everything other than Corvettes and full-sized-B-Body Chevrolets (Caprice, Impala, Belair, Biscayne). Given that the external block dimensions, and all of the bolt-up points on the 396 c.i. cars that he ordered in for his dealership were identical to the 427, he had his parts department order in a 427 and in a few hours, it was swapped in, leaving a 396 block to sell.
Due to adventurous dealerships like Yenko Chevrolet and Baldwin Chevrolet, enough public pressure was made to remove GM's 400 c.i. limit, and the game was 'officially' on! In my world, we call guys like Don Yenko and Joel Rosen (Baldwin Chevrolet/Motion Performance) hotrodders and visionaries.
