And the 71 340 with the 800 cfm t-quad makes more HP than the 625 AVS, OH…. and the 340’s with the 1350 cfm Holley 6 pack ( 950 actual cfm) make even a little more !!
They measure 2V carbs at 3 inches of mercury and 4V carbs at 1.5 inches. So three 2V carbs do not flow 950 CFM if measured at the same pressure drop as a 4V.
