I am curious why they picked this particular model to reproduce??? The Holley 1904 is available in two different flange sizes (like the Rochester B) and several different internal venturi sizes for use on engines from 144 to 305 CID; and used ones (except the ones for the 144) are much more common than even the Rochester B. We have way more than 100; and I never really tried to buy them, just got them in large purchases of other carbs. And even the warpage is much easier to straighten than the Rochester, as there are no projections on the surface to straighten.

Just my curiousity wink
