HOLLEY BILLET BASE PLATE 850-1000cfm Great upgrade or replacement part for a Holley carburetor.
This is an 850 cfm solid Billet aluminum base plate with universal throttle shafts as pictured. This will work for ALL 850 cfm 950 cfm and 1000cfm mechanical secondary Holley carburetors.
Some other carburetors may have a different primary throttle shaft but if it is between 850 cfm and 1000cfm mechanical secondary this will work.
