Cool find and impressive to see. But I have more questions than answers. . . . According to an online calculator, a 289 c.i. race engine at 8000 RPM requires less than 750 CFM of air flow. So two 400 CFM carbs would provide more than enough, and that leads to my question. Is there a performance advantage in running two smaller carbs over one larger carb? I can imagine it might help improve the air signal on a smaller engine to have all the air going thru one of the smaller carbs at lower power levels. Was that the principle behind dual carbs or did folks back then just think two was more than one?
