the 5200 is a progressive two bbl. the 38 mm Weber is not. So the adaptor was somewhat of a restriction on the 235. On the 261, the 5200s still ran well even with the adaptors but yes, I am with .you, would have run better if on 2x2 intake. The 38 mm runs better throughout the rpm range, a lot better. I have Clifford long tube headers for the sound. The shorty headers should similar
