360 Magnum 6 Pack, serious eye candy

Great the small Rochester 2’s are 278 x 3 equals 834 which will be plenty to feed my 360 magnum
Now recalculate to 4bbl. flow rates.
The Holley 6 pack Chrysler used is 1350 cfm as a 2bbl. When converted to the 4bbl. flow rate, they are 955 cfm. That’s a 395 cfm difference.
