[YENKO DEUCE REGISTRY]

In '68 they were both Chevy II and Nova's - the only year for the dual designation. Then in '69 they were only Novas.

A for Don's designations, the '69 Yenko SC is self explanatory. The '70 Yenko Deuce is still a little of a mystery, we believe he was referring back to the Chevy 'II' terminology - but we are not definite. Some have suggested that he refrained from calling the '70 Novas Yenko SC to differentiate them from the 427 models thereby not causing the insurance companies to catch on to the true performance and ruin his idea behind the LT1 etc... Others have suggested that Don used the Deuce term to indicate the Yenko II in comparison to it's bigger engined '69 counterpart - in a similar fashion as GM had done with the original Chevy II and the bigger Chevy I's so to speak. There are more theories as to why the '70 Yenko Novas were so prominently decaled as Deuces, but you get the idea. In short, we really don't know for sure!
