Edelbrock Street Ram on a 408?!?

I ran a tunnel ram on a street driven 460 powered Ford Fairlane for a while. It was absolutely frightening above 3000 RPMs. Below that it was just OK. I took the tunnel ram off and put on a weiand stealth dual plane and couldn't believe how much more low end power I had. The difference was dramatic. It was so much nicer driving with the dual plane, But two fours sticking out of the hood is just too cool!
