Thats the real question is depression you want to run at full throttle not how much cfm.

I don't know what a restrictor plate flows but it's lot less then what a nascar engine needs, the air still gets minus the pumping loss hp cause of the restriction. My cousins late model pulls to 6500 plus through a two barrel.

Cam & compression makes that possible, NOBODY chooses that strategy, long aggressive cams give more time & get the port flow up & sustained so they gasp as much as possible. Then You squeeze the poop out of what You manage to get in there. Time-bombs in NAPCAR prompted the rules for locking up the engines & shocks they qualified with.
