Wow! Do you mean that if a WCFB were used on an Offy or Clifford on a 250 Chevy the adapter plate that everyone talkes about that goes with the manifold would not be needed? What other carb would fit without the plate? 4gc Rochester? From my limited experience with the 4100, it's very simple and easy to tune. I ran a 2100 on my 79 250, the 4100 is almost two of them stuck together. I looked on E bay for WCFB carbs. They aren't all that bad price wise unless the word Corvette is involved. I agree that bigger is not always better. That 1.08 autolite 4100 sounds like something I would try if I had the 302 in question. One thing that IMHO needs added to the discussion is what are the airflow requirements of the 302. Does it have head work or a hot cam? Is the head design good or bad? Jay
