My 1972 Holley book says the 1V 1920 with a 1-11/16" bore flows 235 CFM @ 3.0 inches HG.

The 1945 is not listed since it was not released yet.

It depends on the bore size. The 1920 released for the 170 does not flow as much as the larger 225 version per the Holley Carb manual.

Interesting article though! It puts flow rates into context with the different models.

Thanks for sharing your findings.

Fish? I am confused........ :shock:

Wish he had how much a non super six BBD flowed.

How is a 350cfm Holley rated? And how does it compare to a 1 1/2" BBD for a 383 flow?
