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.

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.

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.
