Is that an Eddy AVS or an OE AVS? If there's enough demand that Holley offered a dual feed I'd think you could possibly starve an Eddy also tho I'm presuming a racing app and one of the Eddy AVS's that are larger CFM. The OE's are pretty small so would pass less fuel so might not hit the wall w one of them. It is a nice touch to drill/tap a dual feed & as as you know larger needle/seats are avail


It's an Edl 650 thunder series carb, that I believe is a little lean as plugs were white. I was going to order a set of metering rods 2 steps richer, and saw the dual feed line in the catalog and thought that might help the performance. The car seems to lack the higher RPM power. (383-30 over trw flat tops - comp cam474/474 - tti headers - rpm performer)
