So did Stromberg:

I have one my dad got years ago tried it on a race motor bogged bad but when it caught up wow did it go. recently a guy gave me a squirter so the rear gets the pump shot also. has long tubes to reach the back.

 

Wonna get rid of it???

 

I know where there are several. I owned one at one time.

I don't know if they still make 'em so what I say may be wrong but the biggest beaf that anyone had with them back here is that you had to retune when there was a major weather change like from summer to winter or humid to dry. Of major al***ude change. They were tempermental in that aspect.

 

WOW! VERY cool.

 

Yes, and it was a monster! In 1968, I had a 64 Impala SS. I dropped in a 396 with an L-88 cam, Holley 1050 3-barrel, and ****** headers, all backed up with a Munci M-22 and a 4:11 gear. When you put your foot in it, that 3 barrel did more than any 4 barrel I ever had.

 

Just a suggestion Dave...your first post should have been an introduction in the appropriate section, and please check the date of the LAST post in the threads you dig out of the archives.....

 

My Father ran one on his Anglia back in the 60's, 70's. Islip actually had a cl*** (Three barrel cheater) sat under the bench at the shop for years after that, don't know where it went.

 

Back in the 60s I ran a speed shop and was a jobber with Gratiot Auto Supply. When the 3 barrel was announced I ordered 2 of them. It was a couple weeks before they actually came in. When I picked them up Angelo told me I had the first two in Michigan. My neighbor kid was building a 60 Chevy hardtop, and I sold him the first one complete with the big tapered air cleaner. He had I believe a 331 cube 327 strong gears we had to play with it a little to get the big secondaries opening correctly but it performed pretty well. The 2nd one went on an asphalt roundy rounder.

 

I remember these on Fords of the late 60's early 70's. ditto on the major bog

 

Had one on a 426 hemi ran better and got better milage than the dual fours.

 

-------------------
Back in the late-'60's-early-'70's an
aftermarket accessory company called
Segal used to make a kit specifically for
the Holley 3-bbls (and also for most Holley
4-bbls too) to convert them to mechanical
secondaries The kit eliminated the vacuum
diaphragm and replaced it with a pair of
nylon gears that attached to the throttle
shafts. Also included in the kit was a
special 'four-hole' accelerator-pump
squirter, to provide a shot of fuel to the
now, mechanically-operated secondaries.
Even with the four-hole accelerator pump
squirter though, converting a 3-bbl to straight
mechanical operation usually resulted in
a m***ive bog. And then when their
'modification' didn't work. people usually
blamed the carb. The 3-bbls in particular
got a bad rep, but mostly because a lot of
people using them didn't know how to - or
that you even could - tune the secondaries
by playing with different diaphragm springs.
The knowledgeable people of the day (- ie -
those who actually understood how a
vacuum-secondary carb works!) kept the
vacuum-operated secondaries and instead
of trying to make them operate mechanically,
played around with different diaphragm springs
until the secondaries were dialed-in to what their
engine wanted and needed. Once properly set
up though, ***uming you had an engine that
could take advantage of the 950 or 1050 cfm
flow potential of these carbs, they were killer
- even on the street.

The heavy "black" spring did the trick.... Most of the time...

 

I had one of those kits a couple years back on my daily driver on the 450 holley, funky feeling petal but worked OK, It wore out the secondary shaft (it was an old carb when i got it)so i threw a different holley on there.

Eelco also had an identical kit too

 

Not only have I heard of them I own two.....one of which belonged to the late great Grumpy Jenkins, it is a 950 and has had the secondaries changed to mechanical as well as some other modifications....they obviously worked or the Grump would not have had one....looks like it may have been dynoed on some stuff cause it has odd holes ,,I believe they are sensor holes

 

Had one on a 66 satellite with a built 383 ,4-speed.You really couldn't nail it until at least 3 grand or it would bog out bad . When the rpms where high enough it was unreal.

 

I have a new squirter with the tubes for the secondarys if any one is interested.

 

Seb, I want that. I'll send you a pm.

 

I have two, the one on the right is NOS and has never had fuel through it, I ran the one on the left on the 440 in my old duster. Ran really good (11.0's @ 121 early '80s, street driven car), my guess is the guys talking about the bog with these carbs were probably missing the check ball from the p***age to the vacuum pot.

 

They actually quit making them because the dominator came out, and believe it or not, the dominator was cheaper to make. The 3bbls were an expensive carb to produce.
And the carb that was developed for Ford for NASCAR use that they didn't want to share with Chrysler was the 4500 dominator, not the 3bbl.

 

I have had a 1050 and still have a 950 with the mechanical conversion somewhere.
The one good thing about them is you can get 1050 cfm carb for a 4150 flange intake.

 

Dunno if you guys are interested, this has been stashed in my top secret carburetor binder for around 40 years. Geez, I don't know .15 and 2 mph over an 850 on a BBC seems ok to me... Jay Brown also tested a 1050 against several other state of the art 4150 flange carbs in his FE book as well, it held its own pretty damned good. Made 15hp more than an annular discharge 1000 cfm Holley HP...

 

from Jay Browns book. Note that none of the out of the box carbs outperform the 3 bbl, it swaps places a couple times with the Barry Grant downleg, has a clear edge over the Holley 1000hp. The only carb that's clearly better is the custom carb from Blair Patrick. This was on a 427 FE with a Victor.

 

Here's one

 

That would be a 1050 ^^^
The graft makes the Holley look more street friendly.

 

were they not manual linkage on secondarys?? bought a new one long ago and tore it down for parts and when selling out the stock car stuff , re***embled and sold it , they were real cheep on a sell out in the 70 s , I don't think I ever used it

 

No, the manual secondary conversion was aftermarket. I paid $25 back around 1979 or 1980 for the 950 I ran on my duster.

 

I have a buddy who has to of them One is 950 Brand new in the original box and the other is a 1050 and it is on his 100 over 454 with all roller valve train and camshaft. Hang on to your a$$ when it hooks up totally awesome throttle response.

 

In a 1959 Corvette I ran a 327 .30 over 12.5 to 1- it also loved Sunoco 260 and broke lots of drive train parts- my dad got tired of helping repair-

 

I used a 950 on my stock car back in the mid 60's, they work great, I would like to use one today but they are hard to find and cost a bunch.
