That test should not be used to judge the small block Mopar intake at all. There are so many choices for big block Chevy and that Trick Flow did fine in the test, there just happens to be many others that came out ahead on that particular engine.
What I would like to see is for someone to get their hands on one of these Trick Flow small block Mopar intakes and compare it directly to results they have on an Edelbrock Victor 340 intake.
