Here is a picture of the original owner of my Camaro that supposedly was sitting in the showroom with some Yenkos (was there from June to Nov69). He said that dealership pumped out high performance, and their shop was not half bad. They were doing some of their own conversions through the service shop, outside of Yenko, and promoted L78's (and all you have to do is change the short block, or bore it). They can do it or you can do it. This is what they told the original owner of my car. You get the 4:10, the curved neck radiator, cowl induction, etc.
