Six pack on 318

May be able to get a way with a little less than that.

It has more to do with CID and RPM.

I think it is CIDXRPM divided buy 3654.

Lets say
318X6000 divided buy 3654=522CFM
A lot of times people go bigger than what they need. So lets say even 650-700 would be plenty.


So I would say 1200CFM is a little much unless you are making some power.


But then the nice thing about that set up is you can put around on just one 2bbl untill you need the other two. So? May work out with less. What is your motor set up?
