Here are the K&N air flow figures for air filters that will fit the Stellings & Hellings air cleaners. Prepare yourself.

E-2570 is 290 cfm, E-2600 is 338 cfm and E-1025 is 389 cfm.

I never thought about buying a dual four setup and running twin holley 360's but now maybe I have an excuse!

So for daily use, looks like I will be stacking them. I might rap them in a pre-filter wrap simply for appearence sake.

If these are accurate 'real world' numbers, Ouch.

Speed220mph, you mentioned that you where going to do some flow tests. Any news on that front? Did you read K&N's flow test procedures? If so, anything we should know about that?
