[quoteyou're correct on size. the 950cfm rating is bogus.



Or is the 850cfm rating bogus? Or is the 1000 cfm rating bogus on the HP carbs which have the same size venturis and throttle plates as the 4781 850s??

Or should all CFM ratings be taken with a grain of salt?

The 950 PF main body venturis are smaller than the Holley 950 main body.
