Can anybody help me ID what cfm they are??? I measured the venturiis against a 4779 750 cfm dhouble pumper I have and the venturis are smaller. 4160 venturiis primaries about 1 1/4" secondaries 1 5/16" The butterflies on the throttle plate on my 4160s all 4 measure 1 9/16" and have the following numbers: 109 primaries 268 secondaries any clues???
