Victor340 and RPM manifold testing

Icetech said

So, i have a question since we are talking flow here... Is there a reason to get nuts with CFM if you don't have the inches or plan to run the RPM that needs 330? I already figure OOTB TF's are overkill for me.. is anything lost lower down by not having huge CFM? Or would having massive CFM and not using it be detrimental below X RPM due to lost velocity?

On an Speedmaster, Edelbrock, TrickFlow type of head it’s almost impossible to slow down the speed to much. I may get called a lier again for saying this but the old Airwolf heads had a 220cc intake runner. Dr J approached Edelbrock to fill in the floor of their heads so he could remove more material. That he did but in doing so he lowered an already piss poor short turn. Sure the head flow lots of cfm but if you would see that jumpy son of a gun on my flowbench you would scratch your head like I did. 308 to 320 down to 310 up to 324 down to 312. You can hear the air pulsing as it skips the short turn and crashes into the good air in the back of the port. If you offered me a set for free I wouldn’t drive 10 miles to pick them up. And you can port a head to flow 310 and still flow good at .300.
