1967 z/28 Holley List #3911 smog Carb - Rare

[Jonesy]

One of the only good 1967 dated 3911's in existence.
If you own a 1967 Z/28 or 396/375hp with smog this is the carb you need.
Dated 752 it is not a service replacement.
Professionally rebuilt by Eric Jackson, this carb is ready to bolt on.

$4500

Why does this look like the previous date was ground off and then restamped to the left of it? Note date location on your 3910 carburetor compared to your 3911.

If I may step in here;

The carburetor was like that when Mike received the carb, and when it arrived to me for restoration.

This is not the first time I have seen this done, and I am very, very confident that this was done when the carburetor was new, and that it was/is not an attempt to alter the date, but more likely a factory repaired mis-stamp. (There are a few other things that I don't wish to disclose on a public forum that also lead me to believe this is a factory stamp) I wouldn't think Holley would have scrapped an otherwise perfect carburetor over a mis-stamp.

FWIW, ever seen a double, or even triple-stamped Holley metering block? I've seen a bunch of them.

I have seen at least a half-dozen other Holley carbs with what I consider to be a "repaired" date from the factory. Some of the other carbs I've had in I am absolutely certain had been like that since day one. An example would be an apparently rather large run of Holley LIST 3418 carbs which were produced in 1970. I have seen numerous examples of that particular carb that had their dates ground off exactly as seen above and re-stamped. It wouldn't make much sense for someone to go to all the trouble to make such an obviously poor attempt at altering a date on an otherwise low-value carburetor.

If I had any questions about the legitimacy of this carb, I would've declined to perform the restoration.

Thanks Eric. This carb was definately not restamped by me or anyone. It was in a pile of old carbs and sold to me as a Mustang Holley core along with a 65 Corvette Holley. The guy that sold it definately did not know the significance of this carb. I have pics of it when I bought it. It was missing pieces, but all the important one were there.

[VintageMusclecar]

You're most welcome Mike.

New price $3295.

Here's a little something to sweeten the deal, both for Mike and whoever might be interested in this carb;

Seeing as how I've made significant progress in my process(es) in regards to both form and function since Mike originally sent this carb to me for restoration, should any paid sYc members purchase this carb, if Mike will be kind enough to drop-ship it to me first, I will re-restore it to bring it up to current standards and ship it to the buyer on my dime. (48 state only)

Again, this offer is for PAID sYc members <u>ONLY</u>

Okay, still have this beautiful Carb. New price $2900. Will listen to offers.

In light of a fairly adamant phone call I just got regarding this carb;

I stand by my earlier statements regarding this particular unit. That being said, for the record I am not making any "official" claims as to the authenticity of the date since it has obviously been altered, and short of a means to travel back in time...

Like I said, I've seen a number of factory mis-stamps, and I believe this is another example, but believe whatever you want about the carb.

(It's times like this that make me miss the old days of rebuilding 3310's and 4781's for the local hotrod crowd http://www.yenko.net/ubbthreads/images/graemlins/rolleyes.gif )

I believe that is the case -that this was done by Holley back when this carb was made. I got this carb this way from a guy on ebay who had no clue as it was listed with a Holley 2818 car as Mustang Holley cores. I purchased it with the buy it now and took the chance that it was the real deal. I sent Eric many pictures to verify it once I got it. The base was all plugged and hacked on and Eric was lucky enough to find me a good base for it. If I look even closer at the grind out I think it was 732, but cant say for sure. This is the real deal and I have never seen another. I have since sold my 67z/28 that was sold in California, hince the smog carb was correct. At the time of the sale I offered this carb to the buyer of the car at a very fair price, but he was not interested. The is the holy grail of all Holleys in my opinion.

I'll post some pics as found. I wish I would have copied the original ebay ad. The following pics are the exact same ones I sent to Eric to verify it.

It was also missing some parts that Eric could easily replace.
