LEGAL CARB #'s for ss/mod
 

does anyone know which part numbers are legal for ss/mod? the rule book says you can use an nhra aprroved 750 cfm rated carb. but i can't find anymore info, i have tried to call nhra 3 times but can't get an answer. div 1 says i have to call california. but no-one out west has returned my calls.

I think you can find the list in selected issues of ND.

If you want the best legal carb for the class, call Dale Cubic at CFM carburetors. He will build the right legal carb for the class.

I got the 750 Demon with air horn approved when I ran the Buick V6 in SS/DS. I still have it. I'll look tomorrow to see if there's a # on it.

thanks guys.

Re: LEGAL CARB #'s for ss/mod
 

No # on the carb, but here's the link to the page on the BG site. I paid about $700 5 years ago but once you get it there's nothing more to do but tune it.

Re: LEGAL CARB #'s for ss/mod
 

On the BG site it looks like the number for the 750 is Part # 1402010DR
750 Competition Speed Demon.
I've been alternating between an old 4779 holley by DaVinci and a DC Carbs (David Cook) 3310-1 when running SS/DS. Neither carb is bored to the max oversize. They go through Tech real easy.

Re: LEGAL CARB #'s for ss/mod
 

this may be a stupid question but are you alowed to mill-off the choke airhorn?

Re: LEGAL CARB #'s for ss/mod
 

YES--Get a rule book look at page 160 gives you any allowable mods and also what you CANNOT do--Comp 387

Re: LEGAL CARB #'s for ss/mod
 

Don't spend a lot of money for the right carb and then have to throw it away. You can remove the choke blade but you can NOT mill off the air horn. That's why BG made these carbs with an air horn, so they were legal for SS/Mod. Read the page I linked to.
