Carburetors for 85 and 95 H.P. Engines
Manufactured by both the Ford Motor Company and the Holley Carburetor Company this carburetor (91A-9510-A) was installed randomly upon the assembly line.

Similarities of the two carburetors were:
Finish was bare diecast.
Bases were cast iron and painted gloss black.
Exterior hardware was cadmium plated.
Steel linkage was stamped.
Idle mixture adjustment screws were brass. The slotted heads of these screws were 5/16" in diameter. Cadmium plated springs kept these adjustment screws from moving.
An elongated vent hole in the upper body was evident.
Cast upon the rear side was “94” within a 3/8" diameter circle.
Cast upon the right side was the Ford script.
It was fastened to studs in the valve chamber cover with three hex nuts (33798-S7) and three lock washers (34846-S7).
The carburetor base to valve chamber cover gasket (40-9447-B) was dark gray in color with a shape very similar to the base of the carburetor.
Features unique to the Holley carburetor were:
Cast upon the left side was “MODEL 91-99” within a ½" diameter circle.
On the right side, cast upon the accelerator pump housing was “H” to indicate Holley manufacture.
Cast upon the left side, atop the fuel bowl housing, was “U.S.A.” in 1/8" tall letters.
Features unique to the Ford carburetor were:
Cast upon the left side was “MODEL 91-99” in two lines with approximate dimensions 3/8" high x ¾" wide.
Some of this model had “15/16” cast upon the left side.
On the right side, cast upon the accelerator pump housing was “F” to indicate Ford manufacture.
Cast upon the left side, upon the fuel bowl housing, was “U.S.A.” in 3/16" tall letters.

That carburetor is for a V8-60.

Unless you have a 60 HP engine in your car (they were available), hang on to it as it as quite valuable.
 
The carburetor (922A-9510-A) used on the 60H.P. engines was manufactured by both Ford Motor Company and the Holley Carburetor Company.
Externally this carburetor was very similar in appearance to the 91A-9510-A carburetors described above.
External differences were:
Cast upon the left side was “Model 92”.
Also cast upon the left side was “13/16”.
Cast upon the rear side was “81”.
 
the correct 91-99 has a float bowl vent on the front of the carb. Only carb for the crank mounted fan. right? Newc
 
Newc,
Please read post #2 carefully. That should, I hope, help you determine what carburetors were correct for the 85 / 95 engines.
