The size of carb(s) or CFM required for a given application can be calculated by the following formula A: {(CID x RPM) ÷ 3456} x {Boost ÷ 14.7) + 1} = CFM required. The amount of CFM required will determine carburetor size and quantity. If you try to use a carb with less CFM than required, performance and economy may be greatly reduced.

434 x 6000 / 3456 x10 / 14.7 + 1= 1,265 cfm

YOU LOST ME ON THIS...... 1,265 CFM= 2 650CFM CARBS
