One pair of Holley 660 Center Squirter Carburators. Numbers on Carbs are "List 4224-S" and Date Code 2167, stamped the same on both carbs. I do not know anything about these 2 carbs history other than they were sitting for a long time, and both had red fuel lines attached, along with throttle linkage that leads me to believe they were a pair on a tunnel ram or other du al quad manifold. Will definitely need a rebuild. $400 for the pair, plus the actual shipping cost.
