A set of 600 CFM'S it is! Thanks everyone!

Great information. What about the metering rods though?

Thanks for the info. I have the intake and plan to use it on a future build. Since following this thread,i am now convinced that 600s are the way to go instead of 500s.

I run 2) 750's with the purple shaft cam 440, all good.

The 6 Pack carb set up is 1200 CFM. 500 center and 350 cfm on outboard carbs.

Just the opposite; 350 cfm. centre, and 500 cfm. outboards, for 1350 cfm. total.

And they're on demand,( vacuum controlled)

Thats the way to go. Magic ticket. Pull them out of the box, dont touch them and will run for years.
