427 Camaro Z11 from Dale Chevrolet, Dales Dusters?

Dale was part of the Yenko dealer network, in fact, a few members here have cars from Dale, including Yenko's and COPOs. I've never heard of a engine swap/transplant car coming from there, but maybe someone else has? I'm guessing the term "Dale's Dusters" was likely a COPO 427 car or maybe even a Yenko. The term was likely more of an ad gimmick than a specific car or package. I don't see any mention of a 427 pace car.
