carb spacer

[Bob Gaines]

B2 had a much larger hose nipple.  428 PI had a 1/8 hose nipple. The 66 Shelby did not have any kind of hose nipple.

+1 Thanks Bob! There are other spacers too but the important thing is no fittings , vacuum ports on the B9AZ part. There would be no reason to use the PI spacer with it's additional vacuum take off and the Boss spacer was yet to be invented.

This is an odd ball I came across for sale once. Thin with a PCV fitting. Some kind of service item maybe?



I have no idea if the part left Ford's control in this box or not but this is what it was sold with.



There were several Ford phenolic resin or die cast aluminum four bore spacers without ancillary porting in parallel and tapered designs before 1966. The aluminum ones are not rare. The resin ones are all fairly rare in good to exellent condition. I have samples of most of them. The one I have never found for sale is the 1/2" thick phenolic version Ford used on XHP-260 and HP260 engines with a Ford 4100 carburetor in 1.12 size. (Yep, the big carburetor on a 260. I have one as used on the special 260 4V engines. The small carburetors were not made until years later.)

Dan,that looks like the one use on 68 GT350.

I wouldn't know, no wrenching, only ridden in 1968s of any version. Must be rare, I have only seen that one.

Looks allot like the C3AZ-9A589-C and of course different since it has the fitting on it as mentioned

Here are four different spacers Clock wise from top left:

B9AE-A,  C3AE-C,  C8AE-D,  C8AZ-E



There are a handful of them that look the same and then variations with slightly different specifications

This shows to be for a 67 FE car.

   Dan ,
      I have a similar one except it is a full .375 (3/8ths) thick. I got two , years back and they were in M/T ( Mickey Thompson) packaging . Straight 1/2" dia tube . Not a Ford part.

There were so many circa 1957-68 versions of Ford/Holley pattern 4V Ford spacers before the Boss 302. I have a collection of ones claimed to be original to some Ford or another. Some just differ in the exact size of the bores. Die cast aluminum, engineered material, tapered, parallel, four bores, two paired, open center, vacuum pick up, PCV pickup, solid except sprue locations, open except around bores and perimeter, PCV enters under secondaries, PCV enters in front, as molded, molded with secondary machining, coolant heated, and that's just what I can recall right off. That doesn't count service versions for 289s 1963-67 Ford sold to apply to more than one replacement application.


Fortunately there were not many versions used in XHP-260, HP260, and HP289s in stock 4V induction Cobras so they are somewhat simple to explain to owners and restorers.

   I have a couple of C3OE (hipo only) spacers and one C3OE intake. The C3OE spacer ( 1" thick cast aluminum) will NOT work on a S1MS ( or later ) Holley intake.

Dan, that looks like the one that came on 33XX series Cobras, did you buy it? Does it have Fomoco molded into one side? What are the bore diameters? Some had smaller bores that will not coincide with the 427 3255 carb. I have 2 of the correct ones and never identified what the part number was.

I was out bid, by more than one bidder, a lot but it did have TOP and FoMoCo logo on one face.

In the French film still that sure looks like an 1/8" holley carb insullator gasket to me. They were kind of an off tan color.
