The summit website has the exact same description for both carbs.

comparison

Notes
8896 Designed for SINGLE 4 barrel set ups. Features "soft" progressive mechanical linkage.
9375 Designed for DUAL 4 barrel set ups. Features "soft" progressive mechanical linkage.

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

G-Bob, I love my 1050 8082-3 HP carb. Drives great on the street and works well at the track even though it`s only a 2-circuit, many people I know prefer em over the 3-circuit series.

The 9375 has annular boosters and the 8896 has downleg boosters

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

You`re going to get many replys from many people so the choice is yours........and a tough one it is indeed. Good luck.

The carbs are basically identical. Both have annular boosters and no power valves. The 8896 and 8896-1 comes with .88 jets. The 9375 has .92 jets and the 9375-1 has .86 jets. There are slight variations in the air bleeds, but you will never tell one from the other on the car, other than main jetting.

Monte

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

My ....run the 8896.

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.

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.
