I temporarily shelved this project, mainly because of the lack on initial success and the fact that I realized I was out of my depth for a project like this. Your information will be useful should I ever decide to revive it. One of my rules was this project was that I did not want to modify the Sharp manifold in any way. From some of the posts here, it seems that this can be made to work, although I have strong suspicions that that the carbs are functioning as 2BBL's only. In all actuality, I probably won't get back to this because of the success I have experienced with Rochester 2G's on Merc manifolds.
