Holman-Moody makes hipo camshafts and matched solid lifters.
+1 on the H-M suggestion.  If that doesn't work out, Howard's Cams & Racing Components makes a near identical reproduction of the factory camshaft.

OK, now that we have definitive evidence, I'll retract my statement that the only difference between manual and automatic are the jets.  The primary booster venturi assembly is different as well.  Good to know, thanks Dan!

A big difference between a non-HiPo and a HiPo carb that I didn't see mentioned is the HiPo carb has a cast in stop for the choke just above the primary throttle shaft.  I've seen people weld in a small rectangular piece of aluminum to simulate that stop, but those are crude at best.

Another tell-tail is the boss for filtered air for the choke is left undrilled.  Filtered air is not needed for a manual choke.

Kevin,

Just to amplify Cory's response, I believe that the only difference between the manual and automatic versions, other than the dashpot, are the jets.  The booster venturi assemblies appear to be the same between the two.  The flow rate is either 595 or 600 CFM, depending on which source you read.

As for the spacer, Cory is correct, you'll need one or have massive vacuum leaks.  Looking at the underside of the carburetor, you'll see that it is not flat and that the Cobra intake manifold mounting pad does not extend to out to the limits of the Autolite's base.  I think I used a Canton Racing Carburetor Spacer, 85-154, available from Summit Racing.  It is made of phenolic, is 1/4 inch thick, and lists for $35.  The phenolic will also help isolate the carburetor from heat.  Hope this helps.

delli,

You are chasing the holly grail of Autolite carburetors.  The one you are looking for is a C6ZF 9510-F.  Scarce as hens teeth and can cost as much as $5,000 (maybe more, I haven't checked prices lately).  The Hi-Performance 289 carburetor for a manual transmission car is a C6ZF 9510-C and is much easier to find.  The C6ZF-F carb is so difficult to find, that I had  to settle on a C6ZF-C on my own car and add a dashpot (which is the only difference I can find, although others may have more information.

There is a vendor who sells on Ebay who seems to get them occasionally, Gotta Fish Carburetors.  I don't have any knowledge of his quality of work and I am not affiliated with with this vendor.  Other than that, I don't have any information as to where you might find one.  Best of luck in your search.

Believe it is 16:1, bumped up from 19:1 with standard Pitman and idler.

See attached, screen grab of the link in the article regarding the $852,500.00 number, seems it was a Eleanor from 2020 - not what I'd call a '67 Shelby, but that my opinion...
I just can't wrap my head around the fact that an "Eleanor" would sell for more than a genuine 1967 Shelby G.T.500.  This is what we call "stupid money"...

Any machining of the deck surface can eliminate this date code so if you are rebuilding- make an effort to photograph prior to any
machine work.
Regards R.R.
I explained to the shop that assembled the engine, the significance of the stampings and they masked those areas off prior to cleaning and avoided machining the engine assembly date when they decked the block.  There was no need to machine the oil pan rail.

Here are the Block Assembly Date and the Engine Assembly date from my engine.  While not a Cobra, these stampings still  illustrate what we are talking about.  The date decodes as November 3rd, 1965.  The letters are the initial of the individual who did the work.

Dan, thank you.  That confirms what I suspected would be included in this type of assembly.

Dan, I guess I wasn't very clear in my question.  Let me restate: what was included in the cylinder block assembly?  I would assume that would be the block, main caps, and main cap bolts.

I have to say that I am blown away by the depth of your knowledge regarding this subject.  All of your comments are very illuminating.  Thanks for sharing your information and I hope to hear more from your 200+ pages of notes.

The key dates people look for on 1963½-1964 cylinder blocks are:
-   Casting date, the day raw block casting produced (cast in near starter location)
-   Cylinder block assembly date, the day the cylinder block assembly was manufactured (hand stamped oil pan rail)
-   Engine assembly date, the most important date, the day the engine was manufactured (hand stamped front of left cylinder bank) What versions of what components went into an engine depended on the date of manufacture as Ford was regularly making revisions to old parts and introducing new ones.
Dan, when you say engine assembly date, what is included in that assembly? Would that be the block, main caps, and main cap bolts or would that be the short block? Thanks.

I know Buddy Bar cast the aluminum heads on my 427 and I know they cast most, if not all, of the aluminum parts for Shelby Engine Company, or at least they did.

Buddy Bar Casting Company (https://buddybarcasting.com/), Shelby's goto foundry.

Yes that is from one of their ads. One of two versions. 66 If that is the year being focused on)  would be very early to be able to get your hands on one of those. Know of one fo the first ones to come off the molds and it was the conventional style not the tilt style
I always thought those kits looked pretty cool.  Better still would be if you added on the spoiler rear deck to the front end kit.

I have been looking for a fastback I last saw in the early 1970s. It was a K code complete with all the SA race parts right down to Webers. It was built as a Bonneville car but had fiberglass doors and an aero fiberglass nose. The owner said he had a buddy that worked at SA and he bought the shell and engine parts from them. He said it was a car they had robbed all the spare parts off for the race cars. Not being into Shelby's at the time I paid little attention once he said not for sale. His house got bought and a big church built on the spot - someday it will surface.

That looks like the Fiberfab conversion kit for '65 - '66 Mustangs.  Not many of them around...
