318 alminum intake?

Ide run a Crosswind or typhoon Airgap clone before a performer (basically a aluminum clone of a OEM iron 4bbl intake) , and they are cheaper to boot. Many people are still asking alot for used Performers while the Crosswinds are selling for the same performer used prices new. I got a polished one for $40 at a swap meet. What are you going to pick up with a Performer? 25 lbs off the nose?
