Well the main diff is the 9375 has NO Power valve provisions...Other than that not much else. Even though the 9375 is ment for 2x4 applications, it works pretty good, if not as well as the 8896 on the street, and s single carb application

You sure about that?
I have 3 9375's and 1 8896 in my shop I can go look at. I'm pretty sure the 9375 has annular boosters. The 8896 as far as I know does not? They may not be called downleg slyle on a Dom., but I don't think they are annular? I will look and see

Holley website and summit both show all the 1050 dominators as being annular boosters. I'm guessing the 8896 will be right for my new combo, but wonder now about the 8082. 2 circuit v. 3 circuit

Don't know about Summit, but from Holley, these two carbs are priced the same. No need not to buy a 3 circuit.

Glen, I thought you had a Dominator. You should take yours over to PC Carb in Ontario since they are in your neck of the woods. Every Carb they have built for customers engines and ours has been spot on. They are local and help out with alot when you have them build your Carb.

There are two different versions of both of those carbs, the early 8896 and 9375 versus the newer 8896-2or-3 HP and the 9375-2 or -3 HP and now possibly a newer 8896HP Ultra and 9375HP Ultra I have had, ran and tested both of the early 8896 and the 9375 non HP carbs.with stock jetting and squirters on Skips Duster at LACR, the 9375 was quicker and faster than the 8896 was by less than a tenth, .010, mayby .080 + or - .001 and close to one MPH I have two of the early 9375 and one 9375-3 HP, there is a lot of differences in the stock jetting and some others parts also, the early 9375 made more power on my 518 than the 9375-3 did with stock jetting on the local dyno here in central OR on back to bacb A-B-A testing Not a bunch but around 8 to 10 hp if I'm remembering correctly. I have had my hands on and dyno tested and used at the track several (5 or 6 different ones) stock 9375 non HP and they all where real close on HP on the dyno, maybe 2 to 3 HP max differences, and at the track, .01 to .03 max on back to back runs at the track. Not so on any of the other 1050 dominators that I have tested at the track or on the dyno Same results on several high dollar custom built 1050 Dominators also

Glen-A bit off topic here but I did find a small issue with the 9377 you tried. It is all better now, not sure how it got that way either IMO go with a three circuit carb...As Monte said I dont think you would be able to tell the difference in the two on the same car once sorted out.

All that is not exactly right Cab. There is an 8896, 8896-1 and 8896-2. All 3 have .88 jets, but the -1 and -2 come with a 55 power valve. There is the 9375, 9375-1 and 9375-2. The original 9375 has .92 jets and no power valve. The -1 and -2 has .86 jets and no power valves. There is no 8896-3 nor 9375-3. There are also no 8896 or 9375 Ultra. There is no series of HP Dominators. They are either standard Dominators or Ultra Dominators. The HP series is the standard flange race carb with no choke horn and the Ultra HP has billet blocks and base plate. You know, I DO work for Holley Monte

Monte, my 8082-3 clearly says HP on it and was listed as such.
OK, let me rephrase. ALL Dominators, with the exception of the Marine unit, are listed as HP carbs(but no HP series), however, there are NOT 3 levels of Dominators. There is no Dominator, Dominator HP and Dominator Ultra HP. Dominators are standard or Ultra and that is it. That is all I am trying to make clear here. There is no "in between" series. When Dominators started getting screw in bleeds vs press in, they got the HP name, but they are still just standard carbs, until you go to the Ultra.
Your 8082-3 is a 2 circuit carb, which is obviously a standard Dominator, regardless of the HP tag. The -1,-2,-3 etc, is nothing more than calibration changes, since the original version of the carb came out.

Gotcha.... I also believe another difference is that the new dommys have a flat venturi area on top where the old ones had that lip/raised ring around the boosters.
I've noticed that.
The whole -1, -2, -3 had me totally confused, as I can only find -1 listed as part number on the internet, Holley site, Summit site, etc. Example, 0-8896-1. There is no -2 listed anywhere that I could find.

Glenn, is it more cost effective to buy a Carb from Summit and then have it worked by a guru or to just buy a worked carb from the Guru in the first place?
I suggest you buy the "Ultra" Dominator, part number 80672 for 1050 or 80673 for 1150. These are Holleys answer to "trick" carbs. They have billet metering blocks with interchangeable emulsion jets and idle feed restrictions. The large sight window bowls, adjustable air bleeds and all the other tricks you would send your carb out to have performed on it.

Monte, I went out and looked at my three 1050 Dominators that I have now, two 9375 early versions and the one newer 9375-2 which is the one that I thought had the HP cast into the drivers side, it does not have that. I learned something from you on that I remember Summits site advertising the new "Holleys HP series" Dominators with improved throttle repsonce and so on so maybe that is where I got the HP reference on the newer Dominators. I should check my three 4150 HP series carbs to see if they have the HP cast onto the sides of them I was under the impressiion that Holley had revised the Dominators to become the HP sereis Dominators back 8 to 10 yrs. ago to compete with BG King series carbs and the other after market carb. companys like Quik Fuel, Pro Form and so on and custom carb makers and modifiers like the "Carb Shop, Chuck Nuygtten(SP?) and the others out there. I wasn't aware that Holley had discontinued the newer "HP" type Domiator line and replaced it with the 'Ultra" series line, thanks for that information Some times I "assume" things from readings adds and public inforamtion (marketing) releases in the Dragster and need straight information from someone at the source like your self I hope that I have not misled or provided any misinformation to anyone on this forum that has led to confusion on there parts, if so I'm sorry Now back to work on more projects that are productive like showing the physcical differences from the top view of the early and later non Ultra 9375 carbs, the one that I had thought was the HP type is the three circiut one on the left, you can see the removable bleeds on the top versus the earlier one with two circiuts and non removable bleeds, which is the one that I like the best for a foot brake car

I have the 80672 and it is a great carb. Pig rich on the intermediate circuit out of the box but the nice thing about the Ultra series carbs is that you can replace the fuel circuit jets in just a few minutes and then it is dialed in. I had to drop the intermediate fuel jets about 20 sizes from stock on my carb and then it started to make some serious power on the dyno. Idle and main circuits were spot on right out of the box. Very nice carb and quite a bit lighter since it has the aluminum baseplate and aluminum metering blocks. (I did an article for Mopar Muscle on that carb and its little brother, the 950 UltraHP)
The only serious issue I know of with that carb is that on really powerful motors there might not be enough main well capacity to keep the AF ratio happy at high speed. Some engine builders say that they can't jet them big enough to keep the fuel curve flat on the top end. I'm not sure if that is the truth or a fairy tale but I do know that BLP sells a metering block where they divorce the idle tube from the main well just to solve that issue.
Andy, I ran the 1150 Ultra on a 632 Chevey recently. The motor made 1154hp with a well known "trick" carb on it and 1166hp with an OOTB 1150 Ultra on it. The fuel curve was great, but as you say, it was a touch lean up top. A couple jet changes cleared it right up. Motor made no more peak, but average was better. This motor really needed a 1250, but at this time, the new 1250 Ultra is not ready for release.

My 1050 8082-3 CLEARLY has an hp embosed on the metering blocks for what it`s worth.
When they went to screw in bleeds, the castings were changed, as shown in Cabs post. An early casting of the revised carbs, may or may not have HP cast into it. I have 6 Dominators here of various sizes, but all have screw in bleeds. Some say HP, some don't.

i'm not sure if you guys saw it earlier this week, but we're having a sale on Holley Carbs. that 80672 ultra dominator is just one of many we have ready to go. that's a real sweet carb and the price is right too...

in general terms, i refer to the newer and older 4500 series carbs as: right- "the early style" left- "hp style"
with regards to G-Bobs original question, i'd get the 8896 myself.
