if your 440 is less than 9.0:1 and 224 deg @ .050 intake duration, your best bet is a Performer style. If you choose the Weiand Action + 8009 . It will make more tork similar to the TQ of a CH4B, and look the same. Yet, the top end will run out around 4,800 rpm. The actual Performer will get you good through 5-5200 rpms, making its torque peak a little latter than a CH. The Performer has more plenum volume than the Action + to account for this.

Some people say the runner length is to small on the low DP's and a RPM high rise must be used on a 440.

FYI-Rpm Mani's can be shaved 1/4" for clearance on a dual scoop hood.

Over 224 duration w/3.23's and lets recommend the RPM intake for street use. The RPM can take more radical camshaft than a open dominator intake.

At the track w/ 4.10's the dominator is the good one.
