Hopefully Andy will be forthcoming as always with test results, it should be interesting to see how they all do, if has time enough to try them all. He doesn't seem to have run any ported intakes in the past (that I can remember)?

But I dunno buddy, personally I think with 505CI and the larger port heads, the 4500 plenum might work OK? Hopefully Andy won't make us wait for the magazine article.
