[YENKO DEUCE REGISTRY]

That is very true Eric, the II / Deuce term was a carryover from earlier models, and is the most popular thoery as to why Yenko called them the Yenko Deuce. We have wondered why Yenko didn't call the '69 Yenko Nova SC's a Deuce though, it would have fit into the logic as well. We will probably never know for sure.

The Yenko Ace was on tap for the '71 model year along with the Yenko Deuce. The Yenko Ace was to be another Nova but this time with 15" wheels/tires, and special suspension however I don't recall that it included any real performance upgrades. Neither of them made it to production, I would assume that Yenko may have pulled the plug since there were many dealers that still had '70 Yenko Deuces on their lots - some of which were complaining that they could not sell them (Colonial for eg!).
