pretty cool so I left a post with tom langdon and he told me that although there are no cfm info on these carter webbers, that two of them are like 340 CFM in 4 barrel rating, so (340 cfm)/(.71)= 493 total CFM at 3 hg in 2 barrel form so each carb should be half of that so around 246 cfm each at 3hg, does that sound about right to anyone lol? (The .71 is the conversion factor back to 1.5 hg from 3.0 hg) He also said it would work up to 5000 rpm but not 6000 rpm or so (dont know why I would ever have it that high lol but ok). He actually said he takes his 250 with two these carbs to 5500 rpm no problem so thats good so a 261 shouldnt be too different. So I think that two these are gonna be easier to deal with/tune/dial in than three of these are give me some clearance for a P/S pump
