Holley 9776 Specs
Holley is a manufacturer of fuel systems, and since 1903 the companys workers have made over 250,000 carburetors. These carburetors have been made for vehicles like Henry Fords original Model A, factory muscle cars, and WWII PT Boats and airplanes. The Holley 9776 carburetor is one of Holleys Model 4160 Adjustable Float carburetors.
Part Number, Product Line and Application
The 9776 carburetor is part of Holleys model 4160 four-barrel carburetors. The carburetors are meant for street and mild race vehicles, and they have vacuum secondaries with a metering plate that doesnt have accelerator pumps, power valves or jets. This means that the 9776 will be easier to tune than full race carburetors. The actual manufacturers part number of the 9776 carburetor is 0-9776 -- this number will come in handy if youre asking for information about it from a service technician.
Barrels, Flange, CFM, Choke and Fuel
The Holley 9776 carburetor has four barrels and a square bore carburetor flange. The CFM or cubic feet per minute -- a measurement of air volume velocity in the carburetor -- has been measured at 450. This carburetor does not have a choke and it uses unleaded gasoline for fuel and a single fuel inlet. It comes with a 3/8-inch flare tube fitting to connect to the fuel line and two hose fittings: a 5/16-inch hose fitting and a 5/16-inch swivel fitting.
Secondary, Finish, Ford Kickdown and Throttle Linkage
The Holley 9776 carburetor has a mechanical secondary, but it doesnt have a secondary accelerator pump circuit. The finish on the 9776 is dichromate, which gives the carburetor an orange-red color. The 9776 does not have a Ford kickdown, but it does have a universal throttle linkage.
