[QUOTE="vahunter, post: 354861, member: 6815"] Ive heard the 30/35 intake with more volume doesn't make a noticeable difference. How true that is? Dont know. But if anyone has both intakes laying around plug the carb hole and nipple with duct tape and set it on bench and level the intakes out as close as you can get them. Then fill the intakes with water using a measuring cup keeping track of how much water is in each intake OR Level and plug both intakes fill the smaller 20 or 25 intake with water. Carefully lift over 30/35 intake and drain into the 30/35 intake. THEN Measure from the mounting surface to the water. This could give you an idea on how much volume difference there is. Maybe a gasket thickness? Maybe fab up a spacer? Just thinking out loud... [/QUOTE]
