Jon, I read with interest the side draft carter inquiry. Three carter YH side drafts might very well work. I always wanted to try that set up but the problem with using carter side drafts is just finding them in the first place. I know they were used on the early corvettes, Nash used them on their metropolitans, I guess there are others. But in any event, they are not all that easy to come by. And then you run head first into getting access to some rods for tuning. Main jets are no problem as they use the same main jets as the WCFB carbs (or AFB I forget now. I have a load in the basement but have not used them for some years after I switched to the webers), but the rods are a different story. I have an old print out from Carter with the call out numbers for rods. From my review, the part numbers do not correspond to any kind of progressive metering. It looks to me that as a need arose for a specific diameter or design rod was called out, Carter engineers designed such rod and then the next available part number was assigned. At least that is my take on it. So to really run the Carters and dial them in, you would need three rare carbs, and a real working knowledge of the rods you would need. There is a real learning curve to that.
Don't get me wrong, I loved my Carter YFs when I ran them. If I ever go back to single bbl carbs, or restore a 235 back to stock, you can be sure I will search out a carter variant, but in terms of what is easily available today in a new or easily obtainable carb, the pickings are slim. At least I think so.
