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.
