1158 is missing the spacer between the Autolite carb and the intake manifold. Can somebody provide me with the part number and photos please.
Thanks,
Ross
Ross,
I've never seen a part number for the spacer though I'm sure that one exists. Nor have I ever seen one for sale (again, I'm sure I just missed seeing the add). I just used a 1/4 inch phenolic spacer (Canton Racing Carburetor Spacers 85-154 I think from Summit Racing). What was nice about this one was that it is a four-hole design which will nicely seal the bottom of the Autolite. Good luck.
+1 on the Canton spacers. I am running two on my GT500. It really does help especially during the summer. They are as thin as 3/8" and the sides aren't black so it doesn't stand out like a sore thumb.
You have to do something with phenolic spacers. There are variations but I know you can't run without them and expect to be able to restart a hot engine.
Some 1966 owners use this.
Engineering Number Material Method Parallel or Tapered (P or T) Thickness (in) Bore Size 1 (in) (primary) Bore Size 2 (in) (secondary) Open Underside (Y or N)
B9AZ-9A589-A phenolic molded P 0.200 1.60 1.60 N
No connection to me but a seller is offering two new old stock ones on eBay® right now.
Just for general information. ( Not to impugn on Dan's posting) I tried the factory 390 spacer/insulator. It was only good for about 10 degrees from no insulator. The 3/8" canton spacers dropped the carburetor base temperature 31 degrees. I have a fuel pump phenolic insulator too. I just haven't installed it.
+1 to Dan's suggestion, the B9AZ spacer is what I've heard as well.
The French film we've been discussing shows a good view of the spacer in several frames. The B9AZ spacer is very dark, the spacer in the film looks white so not sure what was used, at least during that specific production period...

Most likely asbestos white/gray material that was commonly used in various gaskets during that time period . I can't remember coming across a asbestos Ford gasket in my searches however.

Bob:
There was a fibrous type gasket that was gray looking from the side and black on top. It had plastic rings where the carb studs passed though. I believe they were to keep it from being over-tightened. You may remember what year vehicle used them. I vaguely remember seeing them some time ago.
To me they always appears to be the blackish plastic/bakolite material when seen in person. Much like the material used for the 59 as well as the 68-70 V8 Ford spacers were familiar with seeing.
This has been on cars from the 1000-1450 or so range
The asbestos spacer/gasket is what was on my 68 GT350 when I got it, April 4, 1972. It was an x-Hertz and still had the iron/Autolite carb set up on it. I believe that it was a double with one under the PCV adapter, and one over it.
Changing that manifold out for a Holley and the lack of heat isolators generally speaking set me off on a decade of solving a hot restart issue that never should have existed.
IF memory serves, it got changed out because it suddenly developed a hot restart problem which in my instant expertise diagnosed as a malfunctioning automatic choke! ;)
In all honesty, I NEVER saw those gaskets serviced by ANYONE including Ford Service parts.
Not to go off on another tangent BUT the gaskets for the Weber IDA's are the same thickness and seem to be the same materials?
In comparing them scientifically to other solutions such as the Going Thing is attempting to do, how dare he attempt to be scientific and logical, I've never seen numbers but they DO NOT seem to be adequate WITH THE HOLLEYS? Webers, yes. :o
So just to shed light on my astuteness, I am currently working on hot restart issues with the dual Holleys. 1/2" black phenolic plastic at this moment seem to hold the most hope. Maybe tomorrow that will change? It depends on what time of day that is? ::)
I just came across what I think is the bottom gasket in my stack for use with exhaust gas re-circulation. I'll post a picture of it later.
I'm confused. Are you guys discussing spacers between the intake and carburetor, or carburetor gaskets on a 1966 GT-350? Thanks
It IS a spacer we are talking about. It HAS to be a spacer because there is a distinct mismatch between the underside of the Autolite 4100 and the Cobra intake. If a gasket alone was used SERIOUS vacuum leaks would be present. My early Hertz car came with a 3259 Holley so no spacer was used. I have seen later ( original) cars that "to me" use the B9AZ spacer. It is important to know that the carb gaskets used @ SAI were an asbestos composition material and with the right camera angle "could" appear whitish as in the posted pictures. The thick fiberous gaskets with round plastic inserts in the corners were NOT made at the time!

I should have known you'd know, Randy. Wasn't there one with a 1/8" vacuum nipple too? I'll look for the answer to today's 100,000 question when I get to Charlotte later. Be safe all.

Boss 302.
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
(http://www.concoursmustang.com/forum/gallery/14/6-080720141809.jpeg)
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.
