I am currently running a Ford Motorsports dual plane intake on my 351W. I have a 230 deg. retro roller hydrualic cam. My dyno results show the torque is falling off sharply at 5000 with peak power at 5300-5500.

I was thinking about trying out an Edelbrock performer RPM to possibly open up the top end to 5800-6000 rpm.

Do any of you small block folks have any experience with either of these manifolds or other similar manifolds for the windsor?
