This is an interesting article I just ran across. Mopar Small-Block Intake Manifold Flow Test

They claim a Performer RPM doesn't flow as well as the LD340, but that it actually makes more power from better distribution.

The thing I found that really helped the LD340 was the equalizer slot cut into the divider. I tried that on some other intakes and it seamed to work. The direct connection manual wants you to cut out more for race applications. I found just the 1/2 inch by 1 1/2 works great on all dual plain intakes
