Description
HOLLEY/QFT BASEPLATE 850 CFM with universal throttle shafts as pictured. This will work for ALL 850 cfm mechanical secondary (double pumpers) Holley carburetors. Some other carburetors may have a different primary throttle shaft but if it is an 850 cfm mechanical secondary this will work.
If you want to add vacuum ports to a Holley hp 1000 or 950 carburetor, this base will work.
