can anyone tell me how to make a 1050 dominator driveable on the street? i want to do some street driving before i put the race motor in. it loads up at idle. some times i can clean it out sometimes it needs plugs. plugs are ngk # 10 7al2 ign. 509 motor 789 h.p 13.1 comp.

Why are you using such a cold plug?

I run a N/A 461 bbc (13.4 to 1 compression) making approx 740 hp and run R5671A-8's.

I do run a 4150 carb though...gonna be pretty tricky and take some work to get a dominator to work well on the street. Not impossible, but it ain't easy either.

Ran a 0-9375 1050 annular discharge on the street for about 2 years ( basically weekends) had 92 jets square 2.5 power valves and a small K@N air cleaner. Only had a 454 with.670 cam and 12.5-1 about 625hp but drove it anywhere.

We had to change the low and mid speed air bleeds to keep it from fouling plugs at idle. I have carb shop prepped 1400cfm dominator on a 633 with 10:1 comp. When we put the carb on we fouled the plugs. The only thing we got to work was changing the low and mid air bleeds. Going up in sizes leans the mixture out. Those plugs sound pretty cold also. Hope this helps.

thanks for the replys. whats the difference between the annular and straight boosters? these are the plugs that came in the motor. would going to a hotter plug help?

I think my freind runs those same plugs in his blown BBC on alky hes running something like 23 psi of boost thats why the plugs are so cold You should proably go up 1 or 2 heat ranges like DOTracer said . Just a thought

Plugs are way to cold for street driving like others have said. NGK -7's would be a lot better. Power valve in the front metering body would help a lot too if you don't already have one.

what number is on the dominator. straight leg boosters or down leg has to do with the mounting position of the booster down leg is deeper in the body for increased signal strength, straight is higher up more air flow less fuel pull over... anluar discharg is a straight booster with more than one feed hole, others have one.. many all around the inside diameter for better fuel distribution they all have diffrent uses...

borrowed my buddys demon 1000cfm. idles good no more loading up. starts breaking up after clicking into2 at about 6500 rpm. pri. jets 85 with 6.5 power valve. 2nd jets 93 with power valve blocked. where are you guys measuring vacum at? i might have to install port in carb spacer. should i step up in secondary jet size?

Did you put any new plugs in it? Might want to go ahead and do that before making any changes to the carb.

I assume you checked the float levels and it's not running out of fuel right? When you say it's breaking up in 2nd, do you mean it has a miss? Is it constant or at a certain RPM? Did that show up with this new carb or when you put the new plugs in it? What are you gapping them at?

a1elec · #13 Post by **a1elec** » Fri Sep 08, 2006 2:17 pm

yes float levels are in the middle of sight glasses. i put the plugs and carb on at same time. i know i should have done 1 at a time. miss is constant after 2nd gear after 6000 rpm. gaps are .35 it pulled strong with the dominator to 7300 rpm.

I'm not sure everyone would agree with me, but I think I'd pull the plugs regap them to say .030 and see if that makes a difference. Anyone else got ideas?

I would check the plugs and gaps again. I might even fire the car when it is dark and power brake it a little and see if there is any arcing going on. When it misses, it huffing (black smoke) at all?
