Dominator Disasters
 

I have 3 Dominators 2 = 9375 3 Circuits

I = Demon 3 Circuit 1050?

My Mopars a 9 Second Bracket Pigs (3200 with me)
500CI and 6500 RPM.

Jeted 84 or 85 Square no power valves

All rebuilt several times and passages checked and rechecked with everything stock and original including air bleeds.

Way Rich at top end!

Any ideas on how to modify.

I am a Stock/Superstock guy and LOST!

Re: Dominator Disasters
 

Make sure you are using the metering gaskets with the question quotation mark for the 3 circuit carbs. Larger air bleeds? Starving for air in high gear?

John,

This is B King from Vegas, hope all is well with you & your family.

I hate Dominators, I can never seem to get them right. We have one on our 68 Camaro SBC. It runs pig fat in bottom to mid range, but we have made a little headway with it.

Anyway, I think part of you problem might be the 9375 model. It was designed for a 2x4 application not a 1x4 combo. Who knows maybe you are set up 2x4. I'll provide the Holley link for that carb.

I would focus on leaning the jet or more HS air bleed. The original jetting is listed @ 86/86.

This page gave me the education to figure out my Dom. I never worked on 1 before past jetting and Now I tuned it pretty good. I was also to rich at idle and wide open. Changing circuitry and IAB, HSB. solved it.

Re: Dominator Disasters
 

I am using correct gaskets for 3 Circuit

Did not the earlier 9375 (Not 9375-1) have only two circuits=
I was lookiing for one of those.

Re: Dominator Disasters
 

BLP makes 2 circuit blocks that I used to convert my 3 circuit.

Re: Dominator Disasters
 

Thanks Jeff!

Do I need to make any further changes other than
the changing them for them to work?

Re: Dominator Disasters
 

No changes. Took about 4 times to get afr decent. Went through a box of brass set screws with drilling out and redrilling . It was enjoyable to work on as the changes were in a positive manner. . I think I used the blue gaskets and drilled open some of the holes in gaskets to match ports.

Re: Dominator Disasters
 

Just remembered. The guide pins for block to carb body were to long. I found out as after turning on pump it poured fuel out. Filed pins alot to make shorter and not bottom out.

This guy does a lot of work on Dominators and I see a lot of happy customers.

You might check with him.

Re: Dominator Disasters
 

I found a Wilson prepared 1050 that I got with
one of the race cars.
We rebuilt it and it seems (?) to run much leaner and
cleaner...At least in shop.
Hope LVMS opens again some day.

Re: Dominator Disasters
 

I have run at least 3 different 9375's on various BB Chevy engines and never had many problems...

A Davinci ran cleaner at idle and around the pits but was NO faster on the racetrack than a stock 9375...

Jetting should be around 92 square and they have no power valves. I've jetted them higher in good air but anything over a 95 jet is not going to flow more fuel due to issues in the carb. passages


I never had one with removable air bleeds and other than jetting and float levels they work well.

You can change the linkage on some to make them progressive and that's how I ran them....

With proper gaskets, good floats and adjusted right they are good for any single carb fairly big cube engine making a lot of power...700-800 or more.

I have a 3 circuit 1050 carb on my present dragster and it is an annular booster carb just like a 9375....

Don't go down the 2 circuit vs 3 circuit rabbit hole.....The 3 circuit can work fine....You can obviously find guys that do endless modifications since there are many carb "gurus' out there but it's always hit and miss with many of them...….Holley built good carbs and unless its damaged putting them fairly close to how they were built usually works best for me...…

On the road racing four of our Stock/SS stuff for 3 Weeks.

I appreciate all the sage advice......I am buying the Beer and Dinner
when we meet up!!!
