cubic inches times max rpm divided by 3456 will tell you what size carb you
will need.

so...

434 times lets say 6500 rpms divided by 3456 = 817cfm that you will need for
your motor.

more rpms bigger carb
that might be true with a reg. motor, but im not sure with that blower.how much boost are you running? 10 lbs. of boost will make a big dif. in carbs. compaired to 6 lbs. and you can get by with less carb. on the st. with the blower than if you are gonna drag race it. what knd of boost do you have and what are you gonna do with it?
