750cfm Holley 4-Barrel with Edelbrock spacer

I am selling a Holley 3310-3 carburetor. It is 750 cfm, square bore, vacuum secondaries, manual choke and has about 200 miles on it since rebuild. It runs great and needs nothing. It also has the dual inlet braided steel line with an -AN fitting. It comes with an one inch thick Edelbrock 4 hole square bore spacer.
All for $220 shipped.
