Just what the title says. How many cc's are the intake runners on the L92 heads stock? Not sure if im in the right section here. I got a 200cc sbc head on my 355 and was just trying to make a comparison for when I build a 6.0.

Wow now that really puts things into perspective...why did I ever mess around with sbc's? Any cfm flow rates?
