I realize this thread is over six months old, but I wanted to add my thanks to you for taking the time to post your experiences with the Daytona carburetor. Having been through (so far) 3 of the original Rochester B units, and having yet to find one which is not warped (and leaking), I have been searching for an alternative and I think the Daytona might be it for my '53 truck with its 216. I'll save the Rochesters for the next owner.
Ditto, I applaud the effort here to test it out.
I’m not sure any of us love the idea of modern aftermarket carbs. And clearly the Daytona isn’t a perfect solution from a design standpoint.
But keeping our old vehicles on the road for another couple decades is going to likely require some creativity and getting comfortable with less than ideal solutions. The supply of B’s in usable condition sucks. The proper YF is not super easy to source and the prices get higher each year.
Parallel example...I like to tinker around with chainsaws. Some OEM stuff like carbs and coils are getting mighty scarce or just don’t exist. Using aftermarket parts of questionable origin is just becoming a way of life. I don’t particularly like it...but it’s just the way it is.
