My 440 Build. Which intake and WHY ?

There is no reason to run a performer on a 440 mopar, none. You engine literally doesn't operate under any load from idle to 1500rpm. Even with the stock flash stall you are above that if you decide to mash the go pedal. Typical too around town it will see idle to 3000, maybe 3500. They make the same power in that range but the RPM beats it up every where else. THe 440 doesn't lack torque, it lacks HP.

If you truly don't really care about performance just run a stock intake, you'll never know the difference.
