 | Constructed around a L78 SS396 model, the COPO 9737 “Sports Car Conversion” put a 140 MPH speedometer in the dash, added a bigger 1.69 sway bar, and installed better cooling components and tires. Yenko’s mechanics then swapped in an L72 427 CI counter-exchange short-block for the line-installed L78 396, using the L78’s heads, intake and accessories. |
| Of the 65 Yenko Camaros built in 1968, 11 were RS/SS Yenko Camaros. Less than half of that number are known to exist today. This example attracted a high bid of $175k against an estimate of $300k to $350k |  |

 | Yenko swapped out the factory 396 in³ short-block for the L72 427 in³ 450 hp. Top bid was $285k in 2018. |  |
